public static class ClasspathUtils.Delegate extends Object
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 recuring pattern. Its usage pattern, as the name suggests is delegation, not inheritance.
Since: Ant 1.6
Method Summary | |
---|---|
Path | createClasspath()
Delegate method handling the <classpath> tag.
|
ClassLoader | getClassLoader()
Finds or creates the classloader for this object. |
String | getClassLoadId()
Computes the loaderId based on the configuration of the component. |
Path | getClasspath()
The classpath. |
boolean | isReverseLoader()
Get the reverseLoader setting. |
Object | newInstance()
Helper method obtaining a fresh instance of the class specified
in the @classname and using the specified classpath.
|
void | setClassname(String fcqn)
Delegate method handling the @classname attribute.
|
void | setClasspath(Path classpath)
This method is a Delegate method handling the @classpath attribute.
|
void | setClasspathref(Reference r)

|
void | setLoaderRef(Reference r)
Sets the loaderRef. |
void | setReverseLoader(boolean reverseLoader)
Delegate method handling the @reverseLoader attribute.

This nested path-like structure can set a path to add to the classpath.
Returns: the created path.
Returns: The class loader.
Returns: a loader identifier.
Returns: the classpath.
Returns: true if looking up in reverse order.
Returns: the fresh instantiated object.
This attribute sets the full qualified class name of the class to load and instantiate.
Parameters: fcqn the name of the class to load.
This attribute can set a path to add to the classpath.
Parameters: classpath the path to use for the classpath.
This attribute can add a referenced path-like structure to the classpath.
Parameters: r the reference to the classpath.
Parameters: r the reference to the loader.
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.
Parameters: reverseLoader if true reverse the order of looking up a class.
