 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" />

Method Detail- 
setNamepublic void setName(java.lang.String name) Name of the loader. If none, the default loader will be modified- Parameters:
- name- the name of this loader
 
 - 
setResetpublic 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@Deprecated public void setReverse(boolean b) Deprecated.use setParentFirst with a negated argument insteadSet reverse attribute.- Parameters:
- b- if true reverse the normal classloader lookup.
 
 - 
setParentFirstpublic void setParentFirst(boolean b) Set reverse attribute.- Parameters:
- b- if true reverse the normal classloader lookup.
 
 - 
setParentNamepublic void setParentName(java.lang.String name) Set the name of the parent.- Parameters:
- name- the parent name.
 
 - 
setClasspathRefpublic 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- a reference to a path.
- Throws:
- BuildException- if there is a problem.
 
 - 
setClasspathpublic 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.
 
 - 
createClasspathpublic Path createClasspath() Create a classpath.- Returns:
- a path for configuration.
