Interface ObjectFilter

All Superinterfaces:

java.io.Serializable

public interface ObjectFilter

extends java.io.Serializable

This interface is used to filter objects. The caller passes an implementation of this interface to a method and receives callbacks that allow the caller to filter the output objects as desired. Filters can either build up state within themselves or can merely block or pass objects based on a filtering algorithm.

Method Summary

java.lang.Object	filter(java.lang.Object obj) The main filtering method on the interface.
void	reset() Stateful filters should implement this interface to allow them to be reset to an intial state.
