All Implemented Interfaces:

FileFilter

public class NumberRangeFileFilter

extends Object

implements FileFilter

Implements a file filter that examines a number in a filename to determine acceptance. This is useful for wanting to process ranges of numbered files in collections where each file has some name, part of which is alphabetic and constant, and part of which is numeric. The test is evaluated based on the rightmost natural number found in the filename string. (It only looks in the final filename, not in other components of the path.) Number ranges are inclusive.

Constructor Summary

NumberRangeFileFilter(int min, int max, boolean recurse)
Sets up a NumberRangeFileFilter by specifying the range of numbers to accept, and whether to also traverse folders for recursive search.

Method Summary

boolean

accept(File file) Checks whether a file satisfies the number range selection filter.
