Class GlobbingPathFilter

  • All Implemented Interfaces:
    EventFilter
    public class GlobbingPathFilter
extends Object
implements EventFilter
    This Filter implementation supports filtering on paths using simple glob patterns. Such a pattern is a string denoting a path. Each element of the pattern is matched against the corresponding element of a path. Elements of the pattern are matched literally except for the special elements * and ** where the former matches an arbitrary path element and the latter matches any number of path elements (including none).

    Note: an empty path pattern matches no path.

    Note: path patterns only match against the corresponding elements of the path and do not distinguish between absolute and relative paths.

    Note: there is no way to escape * and **.

    Examples: 

        q matches q only
    * matches character matches zero or more characters of a name component without crossing path boundaries (ie without crossing /)
    ** matches every path
    a/b/c matches a/b/c only
    a/*/c matches a/x/c for every element x
    a/*.html/c matches a/x.html/c for every character sequence x (that doesn't include /)
    a/*.*/c matches a/x.y/c for every character sequence x and y (that don't include /)
    **/y/z match every path ending in y/z
    r/s/t/** matches r/s/t and all its descendants
