Class DosFilter

java.lang.Object

cryptix.util.io.DosFilter

All Implemented Interfaces:

java.io.FilenameFilter

public class DosFilter
extends java.lang.Object
implements java.io.FilenameFilter

A java.io.FilenameFilter class that filters directory contents according to traditional DOS wildcard conventions; i.e. the filter is split into two parts: a filename and an extension. In each part '*' replaces any number of characters, and '?' replaces any one character.

Note: this is slightly different to the Windows 95/NT conventions, where filename and extension are not treated separately. E.g. "*" in 95/NT matches all files, whereas for this class "*.*" would have to be used.
