Field Detail

FILE_TYPE

static Comparator<File> FILE_TYPE

Sorts files according to file type. Hidden files are listed first, then normal files, all other files and finally the directories.

FILE_NAME

static Comparator<File> FILE_NAME

Sorts files alphabetically according to the file name.

FILE_LAST_MODIFIED

static Comparator<File> FILE_LAST_MODIFIED

Sorts files according to the last-modified time. More recently touched files appear first in a sorted list.

Method Detail

relativeFileName

static Comparator<File> relativeFileName(File relativeTo)

Sorts files alphabetically according to the relative file name from the specified root to the actual file.

Parameters:

relativeTo - the root for the relative file name

Returns:

a comparator for alphabetical ordering of the relative file names

dotDotdotRest

static Comparator<File> dotDotdotRest(File relativeTo)

Sorts . before .. and then all other files.

Parameters:

relativeTo - the root to evaluate the . and .. files

Returns:

a comparator sorting . before .. before everything else

typeAndRelativeFileName

static Comparator<File> typeAndRelativeFileName(File relativeTo)

Sorts files according to file type and then by relative file name. Hidden files are listed first, then normal files, all other files and finally the directories.

Parameters:

relativeTo - the root for the relative file name

Returns:

a comparator first sorting by file type and then by relative file name

timeAndRelativeFileName

static Comparator<File> timeAndRelativeFileName(File relativeTo)

Sorts files according to the last modified time (last touched files first) and then by relative file name.

Parameters:

relativeTo - the root for the relative file name

Returns:

a comparator first sorting by last modified time and then by relative file name
