      org.apache.slide.common.ScopeTokenizer

All Implemented Interfaces:

java.util.Enumeration

public final class ScopeTokenizer

extends java.util.StringTokenizer

Tokenizes a scope.

This tokenizer derives from StringTokenizer and tokenizes a scope in sub scopes. This object is used for Scope matching in the registry. The API of this object is the same as the StringTokenizer API.

Ex : the scope /foo/bar/bar.txt will be tokenized in the following tokens :

/foo/bar/bar.txt

/foo/bar

/foo

/
