Class PrefixFilter

java.lang.Object

be.SIRAPRISE.util.PrefixFilter

All Implemented Interfaces:

java.io.FilenameFilter

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

A PrefixFilter is a FilenameFilter implementation that filters by prefix. Whether to compare on a case-sensitive or case-insensitive basis is determined from the current FileSystem's separatorChar (for lack of a better solution - the java FileSystem class is not publicly visible and at any rate it does not have a method that explicitly declares case senstivity (the best there is, is a compare() method on File objects that could be used for this purpose).

Method Detail

accept

public boolean accept(java.io.File dir,
                      java.lang.String name)

A PrefixFilter accepts a filename if the filename matches any of the prefixes used to construct the PrefixFilter. A filename matches a prefix if the filename's length is equal or greater than the prefix' length and the leading substring of the prefix is equal to the filename. On unix platforms, case sensitive equality is used, on other platforms, equality is case insensitive.
