Method Details

createClasspath

public Path createClasspath()
Create the classpath to be used when searching for component being defined

Returns:
the classpath of the this definition


createLoader

protected ClassLoader createLoader()
create a classloader for this definition

Returns:
the classloader from the cpDelegate


getClasspath

public Path getClasspath()

Returns:
the classpath for this definition


getClasspathId

public String getClasspathId()
Returns the class path id of the class path delegate.

Returns:
the class path id


getLoaderId

public String getLoaderId()
Returns the loader id of the class path Delegate.

Returns:
the loader id


init

public void init()
            throws BuildException
Overrides:
init in interface Task

Since:
Ant 1.6

See Also:
Task.init()


isReverseLoader

public boolean isReverseLoader()

Returns:
the reverse loader attribute of the classpath delegate.


setClasspath

public void setClasspath(Path classpath)
Set the classpath to be used when searching for component being defined

Parameters:
classpath - an Ant Path object containing the classpath.


setClasspathRef

public void setClasspathRef(Reference r)
reference to a classpath to use when loading the files. To actually share the same loader, set loaderref as well

Parameters:
r - the reference to the classpath


setLoaderRef

public void setLoaderRef(Reference r)
Use the reference to locate the loader. If the loader is not found, taskdef will use the specified classpath and register it with the specified name. This allow multiple taskdef/typedef to use the same class loader, so they can be used together. It eliminate the need to put them in the CLASSPATH.

Parameters:
r - the reference to locate the loader.

Since:
Ant 1.5


setReverseLoader

public void setReverseLoader(boolean reverseLoader)

Deprecated. stop using this attribute

Parameters:
reverseLoader - if true a delegated loader will take precedence over the parent
