java.lang.Objectorg.apache.tools.ant.util.ClasspathUtils.Delegate
public static class ClasspathUtils.Delegate
Delegate that helps out any specific ProjectComponent that needs dynamic classloading.
Ant ProjectComponents that need a to be able to dynamically load Classes and instantiate them often expose the following ant syntax sugar:
This class functions as a delegate handling the configuration issues for this recurring pattern. Its usage pattern, as the name suggests, is delegation rather than inheritance.

public void setClasspath(Path classpath)
This attribute can set a path to add to the classpath.
classpath - the path to use for the classpath.public Path createClasspath()
This nested path-like structure can set a path to add to the classpath.
public void setClassname(java.lang.String fcqn)
This attribute sets the full qualified class name of the class to load and instantiate.
fcqn - the name of the class to load.public void setClasspathref(Reference r)
This attribute can add a referenced path-like structure to the classpath.
r - the reference to the classpath.public void setReverseLoader(boolean reverseLoader)
This attribute can set a boolean indicating that the used classloader should NOT follow the classical parent-first scheme.
By default this is supposed to be false.
Caution: this behaviour is contradictory to the normal way classloaders work. Do not let your ProjectComponent use it if you are not really sure.
reverseLoader - if true reverse the order of looking up a class.public void setLoaderRef(Reference r)
r - the reference to the loader.public java.lang.ClassLoader getClassLoader()
public java.lang.String getClassLoadId()
public java.lang.Object newInstance()
public Path getClasspath()
public boolean isReverseLoader()
