Class OrFileFilter

  com.armatiek.infofuze.stream.filesystem.filefilter.OrFileFilter

All Implemented Interfaces:

ConditionalFileFilter, IOFileFilter, java.io.Serializable

public class OrFileFilter
extends java.lang.Object
implements IOFileFilter, ConditionalFileFilter, java.io.Serializable

A FileIf filter providing conditional OR logic across a list of file filters. This filter returns true if any filters in the list return true. Otherwise, it returns false. Checking of the file filter list stops when the first filter returns true. Based on code from Apache Commons IO version 2.01. The main difference is that this class filters objects that implement FileIf, not File. Original author Steven Caswell
