Class AbstractClassFilter

java.lang.Object
  net.sourceforge.servletspy.handler.base.AbstractClassFilter

All Implemented Interfaces:

IContextHandler, ILifecycle

Direct Known Subclasses:

ClassFilter

public abstract class AbstractClassFilter

extends java.lang.Object

implements IContextHandler

AbstractClassFilter prevents passing of subjects to the next IContextHandler in case they are assignable to an element of a set of classes and interfaces. In this case a string representation of the subject is created.

destroy

public void destroy()

Specified by:

destroy in interface ILifecycle

handle

public final void handle(IContext context)
                  throws java.lang.Exception

Description copied from interface: IContextHandler

The handle method of the IContextHandler is called by the engine each time a subject object should be serialized. The IContextHandler may do the serialization itself using the operations provided by the IContext or pass the serialization task to the next IContextHandler by calling the proceed method on the IContext object.

Specified by:

handle in interface IContextHandler

Parameters:

context - The current serialization context

Throws:

java.lang.Exception - To signal serialization problems

init

public final void init(Param[] params)

Specified by:

init in interface ILifecycle

Parameters:

params - may hold an entries with the key CLASSES holding a space separated list of qualified class or interface names to filter out.
