Constructor Detail

Apt

public Apt()

Construtor for Apt task. This sets the apt compiler adapter as the compiler in the super class.

Method Detail

getAptExecutable

public java.lang.String getAptExecutable()

Get the name of the apt executable.

Returns:

the name of the executable.

setCompiler

public void setCompiler(java.lang.String compiler)

Set the compiler. This is not allowed and a warning log message is made.

Overrides:

setCompiler in class Javac

Parameters:

compiler - not used.

setFork

public void setFork(boolean fork)

Set the fork attribute. Non-forking APT is highly classpath dependent and appears to be too brittle to work. The sole reason this attribute is retained is the superclass does it

Overrides:

setFork in class Javac

Parameters:

fork - if false; warn the option is ignored.

getCompiler

public java.lang.String getCompiler()

Get the compiler class name.

Overrides:

getCompiler in class Javac

Returns:

the compiler class name.

See Also:

Javac.getCompilerVersion()

isCompile

public boolean isCompile()

Get the compile option for the apt compiler. If this is false the "-nocompile" argument will be used.

Returns:

the value of the compile option.

setCompile

public void setCompile(boolean compile)

Set the compile option for the apt compiler. Default value is true.

Parameters:

compile - if true set the compile option.

getFactory

public java.lang.String getFactory()

Get the factory option for the apt compiler. If this is non-null the "-factory" argument will be used.

Returns:

the value of the factory option.

setFactory

public void setFactory(java.lang.String factory)

Set the factory option for the apt compiler. Default value is null.

Parameters:

factory - the classname of the factory.

setFactoryPathRef

public void setFactoryPathRef(Reference ref)

Add a reference to a path to the factoryPath attribute.

Parameters:

ref - a reference to a path.

createFactoryPath

public Path createFactoryPath()

Add a path to the factoryPath attribute.

Returns:

a path to be configured.

getFactoryPath

public Path getFactoryPath()

Get the factory path attribute. If this is not null, the "-factorypath" argument will be used. The default value is null.

Returns:

the factory path attribute.

createOption

public Apt.Option createOption()

Create a nested option.

Returns:

an option to be configured.

getOptions

public java.util.Vector getOptions()

Get the options to the compiler. Each option will use '"-E" name ["=" value]' argument.

Returns:

the options.

getPreprocessDir

public java.io.File getPreprocessDir()

Get the preprocessdir attribute. This corresponds to the "-s" argument. The default value is null.

Returns:

the preprocessdir attribute.

setPreprocessDir

public void setPreprocessDir(java.io.File preprocessDir)

Set the preprocessdir attribute.

Parameters:

preprocessDir - where to place processor generated source files.

execute

public void execute()
             throws BuildException

Do the compilation.

Overrides:

execute in class Javac

Throws:

BuildException - on error.
