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" />

@Override
setClasspathback to summary
public void setClasspath(Path classpath)

Set the classpath to be used when searching for component being defined

Parameters
classpath:Path

an Ant Path object containing the classpath.

setClasspathRefback to summary
public void setClasspathRef(Reference pathRef) throws BuildException

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:Reference

a reference to a path.

Exceptions
BuildException:
if there is a problem.
setNameback to summary
public void setName(String name)

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

Parameters
name:String

the name of this loader

setParentFirstback to summary
public void setParentFirst(boolean b)

Set reverse attribute.

Parameters
b:boolean

if true reverse the normal classloader lookup.

setParentNameback to summary
public void setParentName(String name)

Set the name of the parent.

Parameters
name:String

the parent name.

setResetback to summary
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:boolean

true if the loader is to be reset.

setReverseback to summary
public void setReverse(boolean b)

Deprecated

use setParentFirst with a negated argument instead

Set reverse attribute.

Parameters
b:boolean

if true reverse the normal classloader lookup.
