Class AndFileFilter

  com.armatiek.infofuze.stream.filesystem.filefilter.AndFileFilter

All Implemented Interfaces:

ConditionalFileFilter, IOFileFilter, java.io.Serializable

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

Filters files providing conditional AND logic across a list of file filters. This filter returns true if all filters in the list return true. Otherwise, it returns false. Checking of the file filter list stops when the first filter returns false. 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
