Class FileFunctions.WildcardFilter

java.lang.Object

org.vishia.util.FileFunctions.WildcardFilter

All Implemented Interfaces:

java.io.FilenameFilter

Enclosing class:

FileFunctions

private static class FileFunctions.WildcardFilter
extends java.lang.Object
implements java.io.FilenameFilter

Filter for a file path maybe with wildcards in the directory path. Note: The FilenameFilter is better as the FileFilter because the File.list(FilenameFilter) builds a File instance only if the name is tested positively. In opposite the java.io.File#list(FileFilter) builds a File instance anytime before the test. The difference may be marginal.But java.io.File#list(FileFilter) produces some more instances in the heap, which are unnecessary.
