Method Details

hasCpDelegate

protected boolean hasCpDelegate()

Check if classpath attributes have been set. (to be called before getCpDelegate() is used.

Returns:

true if cpDelegate has been created.

setReverseLoader

@Deprecated
public void setReverseLoader(boolean reverseLoader)

Deprecated.

since 1.6.x. stop using this attribute

Parameters:

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

getClasspath

public Path getClasspath()

Returns:

the classpath for this definition

isReverseLoader

public boolean isReverseLoader()

Returns:

the reverse loader attribute of the classpath delegate.

getLoaderId

public String getLoaderId()

Returns the loader id of the class path Delegate.

Returns:

the loader id

getClasspathId

public String getClasspathId()

Returns the class path id of the class path delegate.

Returns:

the class path id

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.

createClasspath

public Path createClasspath()

Create the classpath to be used when searching for component being defined.

Returns:

the classpath of the this definition

setClasspathRef

public void setClasspathRef(Reference r)

Set a 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, the specified classpath will be used and registered with the specified name. This allows multiple taskdef/typedef to use the same class loader, so they can be used together, eliminating the need to put them in the CLASSPATH.

Parameters:

r - the reference to locate the loader.

Since:

Ant 1.5

createLoader

protected ClassLoader createLoader()

create a classloader for this definition

Returns:

the classloader from the cpDelegate

init

public void init()
          throws BuildException

Description copied from class: Task

Called by the project to let the task initialize properly. The default implementation is a no-op.

Overrides:

init in class Task

Throws:

BuildException - on error.

Since:

Ant 1.6
