Method Detail

checkForUpdates

public void checkForUpdates()

Description copied from interface: UpdateListener

Invoked to force the receiver to check for updates to whatever underlying resources it makes use of.

Specified by:

checkForUpdates in interface UpdateListener

createObject

public Object createObject()

Description copied from interface: ObjectCreator

Create and return the object. In some limited circumstances, the implementation may cache the result, returning the same object for repeated calls.

Specified by:

createObject in interface ObjectCreator

createInstance

protected abstract Object createInstance(Class clazz)

Invoked when an instance of the class is needed. It is the responsibility of this method (as implemented in a subclass) to instantiate the class and inject dependencies into the class.

Description copied from interface: ClassLoaderDelegate

Identifies which classes are to be loaded.

Specified by:

shouldInterceptClassLoading in interface ClassLoaderDelegate

true if the class should be intercepted, false to let parent class loader load class

loadAndTransformClass

public Class<?> loadAndTransformClass(String className)
                               throws ClassNotFoundException

Description copied from interface: ClassLoaderDelegate

Parameters:

className - binary class name

Returns:

loaded and (if not an inner class) transformed class

Throws:

ClassNotFoundException

doClassLoad
