Member Function Documentation

virtual void Ogre::ResourceManager::_notifyResourceLoaded ( Resource * res ) [virtual, inherited]

Notify this manager that a resource which it manages has been loaded.

virtual void Ogre::ResourceManager::_notifyResourceTouched ( Resource * res ) [virtual, inherited]

Notify this manager that a resource which it manages has been 'touched', i.e.

used.

virtual void Ogre::ResourceManager::_notifyResourceUnloaded ( Resource * res ) [virtual, inherited]

Notify this manager that a resource which it manages has been unloaded.

virtual void Ogre::ResourceManager::addImpl ( ResourcePtr & res ) [protected, virtual, inherited]

Add a newly created resource to the manager (note weak reference).

virtual void Ogre::GpuProgramManager::addMicrocodeToCache	(	const String &	name,
		const Microcode &	microcode
	)			`[virtual]`

Adds a microcode for a program to the microcode cache.

Parameters:

name

The name of the program.

static String Ogre::GpuProgramManager::addRenderSystemToName ( const String & name ) [static, protected]

bool Ogre::GpuProgramManager::canGetCompiledShaderBuffer ( )

virtual void Ogre::ResourceManager::checkUsage ( void ) [protected, virtual, inherited]

Checks memory usage and pages out if required.

virtual ResourcePtr Ogre::ResourceManager::create	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	createParams = `0`
	)			`[virtual, inherited]`

Creates a new blank resource, but does not immediately load it.

Remarks:: Resource managers handle disparate types of resources, so if you want to get at the detailed interface of this resource, you'll have to cast the result to the subclass you know you're creating.

Parameters:

	name	The unique name of the resource
	group	The name of the resource group to attach this new resource to
	isManual	Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
	loader	Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
	createParams	If any parameters are required to create an instance, they should be supplied here as name / value pairs

virtual ResourcePtr Ogre::GpuProgramManager::create	(	const String &	name,
		const String &	group,
		GpuProgramType	gptype,
		const String &	syntaxCode,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`
	)			`[virtual]`

General create method, using specific create parameters instead of name / value pairs.

virtual Resource* Ogre::ResourceManager::createImpl	(	const String &	name,
		ResourceHandle	handle,
		const String &	group,
		bool	isManual,
		ManualResourceLoader *	loader,
		const NameValuePairList *	createParams
	)			`[protected, pure virtual, inherited]`

Create a new resource instance compatible with this manager (no custom parameters are populated at this point).

Remarks:: Subclasses must override this method and create a subclass of Resource.

Parameters:

	name	The unique name of the resource
	group	The name of the resource group to attach this new resource to
	isManual	Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
	loader	Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
	createParams	If any parameters are required to create an instance, they should be supplied here as name / value pairs. These do not need to be set on the instance (handled elsewhere), just used if required to differentiate which concrete class is created.

Implemented in Ogre::CompositorManager, Ogre::FontManager, Ogre::HighLevelGpuProgramManager, Ogre::MaterialManager, Ogre::MeshManager, and Ogre::SkeletonManager.

virtual Resource* Ogre::GpuProgramManager::createImpl	(	const String &	name,
		ResourceHandle	handle,
		const String &	group,
		bool	isManual,
		ManualResourceLoader *	loader,
		GpuProgramType	gptype,
		const String &	syntaxCode
	)			`[protected, pure virtual]`

Specialised create method with specific parameters.

virtual Microcode Ogre::GpuProgramManager::createMicrocode ( const size_t size ) const [virtual]

Creates a microcode to be later added to the cache.

Parameters:

size

The size of the microcode in bytes

virtual ResourceCreateOrRetrieveResult Ogre::ResourceManager::createOrRetrieve	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	createParams = `0`
	)			`[virtual, inherited]`

Create a new resource, or retrieve an existing one with the same name if it already exists.

Remarks:: This method performs the same task as calling getByName() followed by create() if that returns null. The advantage is that it does it in one call so there are no race conditions if using multiple threads that could cause getByName() to return null, but create() to fail because another thread created a resource in between.

See also:: ResourceManager::create; ResourceManager::getByName

Returns:: A pair, the first element being the pointer, and the second being an indicator specifying whether the resource was newly created.

virtual GpuProgramParametersSharedPtr Ogre::GpuProgramManager::createParameters ( void ) [virtual]

Creates a new GpuProgramParameters instance which can be used to bind parameters to your programs.

Remarks:: Program parameters can be shared between multiple programs if you wish.

virtual GpuProgramPtr Ogre::GpuProgramManager::createProgram	(	const String &	name,
		const String &	groupName,
		const String &	filename,
		GpuProgramType	gptype,
		const String &	syntaxCode
	)			`[virtual]`

Create a new, unloaded GpuProgram from a file of assembly.

Remarks:: Use this method in preference to the 'load' methods if you wish to define a GpuProgram, but not load it yet; useful for saving memory.

: This method creates a new program of the type specified as the second parameter. As with all types of ResourceManager, this class will search for the file in all resource locations it has been configured to look in.

Parameters:

	name	The name of the program
	groupName	The name of the resource group
	filename	The file to load
	syntaxCode	The name of the syntax to be used for this program e.g. arbvp1, vs_1_1
	gptype	The type of program to create

virtual GpuProgramPtr Ogre::GpuProgramManager::createProgramFromString	(	const String &	name,
		const String &	groupName,
		const String &	code,
		GpuProgramType	gptype,
		const String &	syntaxCode
	)			`[virtual]`

Create a GPU program from a string of assembly code.

Remarks:: Use this method in preference to the 'load' methods if you wish to define a GpuProgram, but not load it yet; useful for saving memory.

: The assembly code must be compatible with this manager - call the getSupportedSyntax method for details of the supported syntaxes

Parameters:

	name	The identifying name to give this program, which can be used to retrieve this program later with getByName.
	groupName	The name of the resource group
	code	A string of assembly code which will form the program to run
	gptype	The type of program to create.
	syntaxCode	The name of the syntax to be used for this program e.g. arbvp1, vs_1_1

virtual GpuSharedParametersPtr Ogre::GpuProgramManager::createSharedParameters ( const String & name ) [virtual]

Retrieves a pointer to a resource by handle, or null if the resource does not exist.

virtual ResourcePtr Ogre::ResourceManager::getByName	(	const String &	name,
		const String &	groupName = `ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME`
	)			`[virtual, inherited]`

Retrieves a pointer to a resource by name, or null if the resource does not exist.

ResourcePtr Ogre::GpuProgramManager::getByName	(	const String &	name,

	preferHighLevelPrograms	If set to true (the default), high level programs will be returned in preference to low-level programs.

virtual Real Ogre::ResourceManager::getLoadingOrder ( void ) const [virtual, inherited]

Gets the relative loading order of resources of this type.

Remarks:: There are dependencies between some kinds of resource in terms of loading order, and this value enumerates that. Higher values load later during bulk loading tasks.

Implements Ogre::ScriptLoader.

Definition at line 412 of file OgreResourceManager.h.

virtual size_t Ogre::ResourceManager::getMemoryBudget ( void ) const [virtual, inherited]

Get the limit on the amount of memory this resource handler may use.

virtual size_t Ogre::ResourceManager::getMemoryUsage ( void ) const [virtual, inherited]

Get if the microcode of a shader should be saved to a cache.

virtual const StringVector& Ogre::ResourceManager::getScriptPatterns ( void ) const [virtual, inherited]

Gets the file patterns which should be used to find scripts for this ResourceManager.

Remarks:: Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).

: This method lets you determine the file pattern which will be used to identify scripts intended for this manager.

Returns:: A list of file patterns, in the order they should be searched in.

See also:: isScriptingSupported, parseScript

Implements Ogre::ScriptLoader.

Definition at line 388 of file OgreResourceManager.h.

Retrieve a set of shared parameters, which can be used across many GpuProgramParameters objects of different structures.

static GpuProgramManager& Ogre::GpuProgramManager::getSingleton ( void ) [static]

Override standard Singleton retrieval.

Remarks:: Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

: This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

Reimplemented from Ogre::Singleton< GpuProgramManager >.

static GpuProgramManager* Ogre::GpuProgramManager::getSingletonPtr ( void ) [static]

Override standard Singleton retrieval.

Remarks:: Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them.

virtual void Ogre::ResourceManager::parseScript	(	DataStreamPtr &	stream,
		const String &	groupName
	)			`[virtual, inherited]`

Parse the definition of a set of resources from a script file.

Remarks:: Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).

Parameters:

	stream	Weak reference to a data stream which is the source of the script
	groupName	The name of the resource group that resources which are parsed are to become a member of. If this group is loaded or unloaded, then the resources discovered in this script will be loaded / unloaded with it.

Implements Ogre::ScriptLoader.

Reimplemented in Ogre::CompositorManager, Ogre::FontManager, and Ogre::MaterialManager.

virtual ResourcePtr Ogre::ResourceManager::prepare	(	const String &	name,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`,
		const NameValuePairList *	loadParams = `0`,
		bool	backgroundThread = `false`
	)			`[virtual, inherited]`

Generic prepare method, used to create a Resource specific to this ResourceManager without using one of the specialised 'prepare' methods (containing per-Resource-type parameters).

Parameters:

	name	The name of the Resource
	group	The resource group to which this resource will belong
	isManual	Is the resource to be manually loaded? If so, you should provide a value for the loader parameter
	loader	The manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
	loadParams	Optional pointer to a list of name/value pairs containing loading parameters for this type of resource.
	backgroundThread	Optional boolean which lets the load routine know if it is being run on the background resource loading thread

virtual void Ogre::ResourceManager::reloadAll ( bool reloadableOnly = true ) [virtual, inherited]

Caused all currently loaded resources to be reloaded.

Remarks:: All resources currently being held in this manager which are also marked as currently loaded will be unloaded, then loaded again.

Parameters:

reloadableOnly

If true (the default), only reload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't loaded again. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.

See also:: Resource::isReloadable for resource is reloadable.

virtual void Ogre::ResourceManager::reloadUnreferencedResources ( bool reloadableOnly = true ) [virtual, inherited]

Caused all currently loaded but not referenced by any other object resources to be reloaded.

Remarks:: This method behaves like reloadAll, except that it only reloads resources which are not in use, i.e. not referenced by other objects.

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of reloadAll allows you avoid fail in those situations.

Parameters:

reloadableOnly

If true (the default), only reloads resources which can be subsequently automatically reloaded.

virtual void Ogre::ResourceManager::remove ( ResourceHandle handle ) [virtual, inherited]

Remove a single resource by handle.

Remarks:: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::remove ( const String & name ) [virtual, inherited]

Remove a single resource by name.

Remarks:: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::remove ( ResourcePtr & r ) [virtual, inherited]

Remove a single resource.

Remarks:: Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::removeAll ( void ) [virtual, inherited]

Removes all resources.

Note:: The word 'Destroy' is not used here, since if any other pointers are referring to these resources, they will persist until they have been finished with; however to all intents and purposes the resources no longer exist and will get destroyed imminently.; If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

Reimplemented in Ogre::CompositorManager.

virtual void Ogre::ResourceManager::removeImpl ( ResourcePtr & res ) [protected, virtual, inherited]

Remove a resource from this manager; remove it from the lists.

virtual void Ogre::ResourceManager::removeUnreferencedResources ( bool reloadableOnly = true ) [virtual, inherited]

Remove all resources which are not referenced by any other object.

Remarks:: This method behaves like removeAll, except that it only removes resources which are not in use, ie not referenced by other objects. This allows you to free up some memory selectively whilst still keeping the group around (and the resources present, just not using much memory).

: Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, remove or reload that resource will cause dangerous pointer access. Use this function instead of removeAll allows you avoid fail in those situations.

Parameters:

reloadableOnly

If true (the default), only removes resources which can be subsequently automatically reloaded.

virtual bool Ogre::ResourceManager::resourceExists ( ResourceHandle handle ) [virtual, inherited]

Returns whether a resource with the given handle exists in this manager.

Definition at line 313 of file OgreResourceManager.h.

virtual bool Ogre::ResourceManager::resourceExists ( const String & name ) [virtual, inherited]

Returns whether the named resource exists in this manager.

Definition at line 308 of file OgreResourceManager.h.

virtual void Ogre::GpuProgramManager::saveMicrocodeCache ( DataStreamPtr stream ) const [virtual]

Saves the microcode cache to disk.

Parameters:

stream

The destination stream

virtual void Ogre::ResourceManager::setMemoryBudget ( size_t bytes ) [virtual, inherited]

Set a limit on the amount of memory this resource handler may use.

Remarks:: If, when asked to load a new resource, the manager believes it will exceed this memory budget, it will temporarily unload a resource to make room for the new one. This unloading is not permanent and the Resource is not destroyed; it simply needs to be reloaded when next used.

void Ogre::GpuProgramManager::setSaveMicrocodesToCache ( const bool val )

Set if the microcode of a shader should be saved to a cache.

virtual void Ogre::ResourceManager::setVerbose ( bool v ) [virtual, inherited]

Sets whether this manager and its resources habitually produce log output.

Definition at line 418 of file OgreResourceManager.h.

virtual void Ogre::ResourceManager::unload ( ResourceHandle handle ) [virtual, inherited]

Unloads a single resource by handle.

Remarks:: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

See also:: ResourceGroupManager for unloading of resource groups.

virtual void Ogre::ResourceManager::unload ( const String & name ) [virtual, inherited]

Unloads a single resource by name.

Remarks:: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.

See also:: ResourceGroupManager for unloading of resource groups.

virtual void Ogre::ResourceManager::unloadAll ( bool reloadableOnly = true ) [virtual, inherited]

Unloads all resources.

Remarks:: Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.
