Class AgeFileFilter
- FileFilter, FilenameFilter, Serializable, IOFileFilter
public class AgeFileFilter
implements Serializable
Filters files based on a cutoff time, can filter either newer
files or files equal to or older.
For example, to print all files and directories in the
current directory older than one day:
File dir = new File(".");
// We are interested in files older than one day
long cutoff = System.currentTimeMillis() - (24 * 60 * 60 * 1000);
String[] files = dir.list( new AgeFileFilter(cutoff) );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}

acceptOlder
private final boolean acceptOlder
Whether the files accepted will be older or newer.
cutoff
private final long cutoff
The cutoff time threshold.
AgeFileFilter
public AgeFileFilter(Date cutoffDate)
Constructs a new age file filter for files older than (at or before)
a certain cutoff date.
cutoffDate
- the threshold age of the files
AgeFileFilter
public AgeFileFilter(Date cutoffDate,
boolean acceptOlder)
Constructs a new age file filter for files on any one side
of a certain cutoff date.
cutoffDate
- the threshold age of the filesacceptOlder
- if true, older files (at or before the cutoff)
are accepted, else newer ones (after the cutoff).
AgeFileFilter
public AgeFileFilter(File cutoffReference)
Constructs a new age file filter for files older than (at or before)
a certain File (whose last modification time will be used as reference).
cutoffReference
- the file whose last modification
time is usesd as the threshold age of the files
AgeFileFilter
public AgeFileFilter(File cutoffReference,
boolean acceptOlder)
Constructs a new age file filter for files on any one side
of a certain File (whose last modification time will be used as
reference).
cutoffReference
- the file whose last modification
time is usesd as the threshold age of the filesacceptOlder
- if true, older files (at or before the cutoff)
are accepted, else newer ones (after the cutoff).
AgeFileFilter
public AgeFileFilter(long cutoff)
Constructs a new age file filter for files equal to or older than
a certain cutoff
cutoff
- the threshold age of the files
AgeFileFilter
public AgeFileFilter(long cutoff,
boolean acceptOlder)
Constructs a new age file filter for files on any one side
of a certain cutoff.
cutoff
- the threshold age of the filesacceptOlder
- if true, older files (at or before the cutoff)
are accepted, else newer ones (after the cutoff).
accept
public boolean accept(File file)
Checks to see if the last modification of the file matches cutoff
favorably.
If last modification time equals cutoff and newer files are required,
file
IS NOT selected.
If last modification time equals cutoff and older files are required,
file
IS selected.
- accept in interface IOFileFilter
- accept in interface AbstractFileFilter
- true if the filename matches
