Class Classloader

public class Classloader extends Task

EXPERIMENTAL Create or modifies ClassLoader. The required pathRef parameter will be used to add classpath elements. The classpath is a regular path. Currently only file components are supported (future extensions may allow URLs). You can modify the core loader by not specifying any name or using "ant.coreLoader". (the core loader is used to load system ant tasks and for taskdefs that don't specify an explicit path). Taskdef and typedef can use the loader you create if the name follows the "ant.loader.NAME" pattern. NAME will be used as a pathref when calling taskdef. This tasks will not modify the core loader if "build.sysclasspath=only" The typical use is:

  <path id="ant.deps" >
     <fileset dir="myDir" >
        <include name="junit.jar, bsf.jar, js.jar, etc"/>
     </fileset>
  </path>

  <classloader pathRef="ant.deps" />

public Classloader()

Default constructor

Method Detail

createClasspath

public Path createClasspath()

Create a classpath.

Returns: a path for configuration.

execute

public void execute()

do the classloader manipulation.

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 pathRef)

Specify which path will be used. If the loader already exists and is an AntClassLoader (or any other loader we can extend), the path will be added to the loader.

Parameters: pathRef a reference to a path.

Throws: BuildException if there is a problem.

setName

public void setName(String name)

Name of the loader. If none, the default loader will be modified

Parameters: name the name of this loader

setParentFirst

public void setParentFirst(boolean b)

Set reverse attribute.

Parameters: b if true reverse the normal classloader lookup.

setParentName

public void setParentName(String name)

Set the name of the parent.

Parameters: name the parent name.

setReset

public void setReset(boolean b)

Reset the classloader, if it already exists. A new loader will be created and all the references to the old one will be removed. (it is not possible to remove paths from a loader). The new path will be used.

Parameters: b true if the loader is to be reset.

setReverse

public void setReverse(boolean b)

Set reverse attribute.

Parameters: b if true reverse the normal classloader lookup.
