Method Detail

accept

public boolean accept(java.io.File f,
                      java.lang.String fn)

Return true if this file matches the pattern in the RE instantiated by the client. If "this" had a date passed in to the constructor then cmpdte is active not null With an active cmpdte, you must also get a File instance from the parms f and fn and get the lastModified from that file for comparison with cmpdte. The file will pass the test if it's newer than cmpdte

Specified by:

accept in interface java.io.FilenameFilter

Parameters:

f - the directory portion of the full pathname

fn - just the name.typ portion. does not include directory information.

Returns:

the pattern matched the name portion. the pattern matched on name and the lastModified asDate was greater than cmpdte instance variable
