Detailed Description

template<ACE_SYNCH_DECL>
class ACE_Module< ACE_SYNCH_DECL >

An abstraction for managing a bi-directional flow of messages.

This is based on the Module concept in System V Streams, which contains a pair of Tasks, one for handling upstream processing, one for handling downstream processing. In general, you shouldn't subclass from this class, but instead subclass from the ACE_Task.

Constructor & Destructor Documentation

template<ACE_SYNCH_DECL >

ACE_Module< ACE_SYNCH_DECL >::ACE_Module

(

void

)

Create an empty Module.

template<ACE_SYNCH_DECL >

virtual ACE_Module< ACE_SYNCH_DECL >::~ACE_Module

(

void

)

[virtual]

Shutdown the Module.

template<ACE_SYNCH_DECL >

ACE_Module< ACE_SYNCH_DECL >::ACE_Module	(	const ACE_TCHAR *	module_name,
		ACE_Task< ACE_SYNCH_USE > *	writer = 0,
		ACE_Task< ACE_SYNCH_USE > *	reader = 0,
		void *	args = 0,
		int	flags = M_DELETE
	)

Create an initialized module with module_name as its identity and reader and writer as its tasks.

Member Function Documentation

template<ACE_SYNCH_DECL >

void* ACE_Module< ACE_SYNCH_DECL >::arg

(

void

)

const

Get the argument passed to the tasks.

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::arg

(

void *

)

Set the argument passed to the tasks.

template<ACE_SYNCH_DECL >

int ACE_Module< ACE_SYNCH_DECL >::close

(

int

flags = M_DELETE_NONE

)

Close down the module and its tasks. The flags argument can be used to override the default behaviour, which depends on previous flags values in calls to c'tor, <open>, <reader>, and <writer>. A previous value M_DELETE[_XXX] can not be overridden. Should not be called from within <ACE_Task::module_closed>.

template<ACE_SYNCH_DECL >

int ACE_Module< ACE_SYNCH_DECL >::close_i	(	int	which,
		int	flags
	)		[private]

Implements the close operation for either the reader or the writer task (depending on which).

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::dump

(

void

)

const

Dump the state of an object.

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::link

(

ACE_Module< ACE_SYNCH_USE > *

m

)

Link to other modules in the ustream stack.

template<ACE_SYNCH_DECL >

const ACE_TCHAR* ACE_Module< ACE_SYNCH_DECL >::name

(

void

)

const

Get the module name.

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::name

(

const ACE_TCHAR *

)

Set the module name.

template<ACE_SYNCH_DECL >

ACE_Module<ACE_SYNCH_USE>* ACE_Module< ACE_SYNCH_DECL >::next

(

void

)

Get the next pointer to the module above in the stream.

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::next

(

ACE_Module< ACE_SYNCH_USE > *

m

)

Set the next pointer to the module above in the stream.

template<ACE_SYNCH_DECL >

int ACE_Module< ACE_SYNCH_DECL >::open	(	const ACE_TCHAR *	module_name,
		ACE_Task< ACE_SYNCH_USE > *	writer = 0,
		ACE_Task< ACE_SYNCH_USE > *	reader = 0,
		void *	a = 0,
		int	flags = M_DELETE
	)

Initialize the module with module_name as its identity and reader> and writer as its tasks. Previously register reader or writers or closed down and deleted according to the value of flags_. Should not be called from within <ACE_Task::module_closed>.

template<ACE_SYNCH_DECL >

ACE_Task<ACE_SYNCH_USE>* ACE_Module< ACE_SYNCH_DECL >::reader

(

void

)

Get the reader task.

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::reader	(	ACE_Task< ACE_SYNCH_USE > *	q,
		int	flags = M_DELETE_READER
	)

Set the reader task. flags can be used to indicate that the module should delete the reader during a call to close or to the destructor. If a previous reader exists, it is closed. It may also be deleted, depending on the old flags_ value. Should not be called from within <ACE_Task::module_closed>.

template<ACE_SYNCH_DECL >

ACE_Task<ACE_SYNCH_USE>* ACE_Module< ACE_SYNCH_DECL >::sibling

(

ACE_Task< ACE_SYNCH_USE > *

orig

)

Set and get pointer to sibling ACE_Task in an ACE_Module.

template<ACE_SYNCH_DECL >

ACE_Task<ACE_SYNCH_USE>* ACE_Module< ACE_SYNCH_DECL >::writer

(

void

)

Get the writer task.

template<ACE_SYNCH_DECL >

void ACE_Module< ACE_SYNCH_DECL >::writer	(	ACE_Task< ACE_SYNCH_USE > *	q,
		int	flags = M_DELETE_WRITER
	)

Set the writer task. flags can be used to indicate that the module should delete the writer during a call to close or to the destructor. If a previous writer exists, it is closed. It may also be deleted, depending on the old flags_ value. Should not be called from within <ACE_Task::module_closed>.
