Filters a list of files based on the specified prefix. Files
having
the specifed suffix are chosen. To choose all files, specify a
empty string as the suffix. Note, the
file name not the entire
path is looked at by this filter. For example, if a file has a path of
/foo/bar/x.html then only
x.html will be looked at by
this filter. (to retrieve the filename, this filter calls
getName() on the input file)
The specified pattern can be a single token or a a comma delimited set of
tokens. For example:
.
foo
.,foo,bar
The above will select all files starting with '.', all files starting
with 'foo' and all files starting with '.' or 'foo' or 'bar' respectively.
