java.io.Serializable
, java.util.Comparator<java.io.File>
public class PathFileComparator extends AbstractFileComparator implements java.io.Serializable
File.getPath()
).
This comparator can be used to sort lists or arrays of files
by their path either in a case-sensitive, case-insensitive or
system dependant case sensitive way. A number of singleton instances
are provided for the various case sensitivity options (using IOCase
)
and the reverse of those options.
Example of a case-sensitive file path sort using the
PATH_COMPARATOR
singleton instance:
List<File> list = ... PathFileComparator.PATH_COMPARATOR.sort(list);
Example of a reverse case-insensitive file path sort using the
PATH_INSENSITIVE_REVERSE
singleton instance:
File[] array = ... PathFileComparator.PATH_INSENSITIVE_REVERSE.sort(array);
