org.apache.commons.io.comparator.LastModifiedFileComparator
- ????????:
Serializable
,Comparator<File>
Compare the last modified date/time of two files for order
(see
FileUtils.lastModifiedUnchecked(File)
).
This comparator can be used to sort lists or arrays of files by their last modified date/time.
Example of sorting a list of files using the
LASTMODIFIED_COMPARATOR
singleton instance:
List<File> list = ... ((AbstractFileComparator) LastModifiedFileComparator.LASTMODIFIED_COMPARATOR).sort(list);
Example of doing a reverse sort of an array of files using the
LASTMODIFIED_REVERSE
singleton instance:
File[] array = ... ((AbstractFileComparator) LastModifiedFileComparator.LASTMODIFIED_REVERSE).sort(array);
