 org.syntax.jedit.KeywordMap
| KeywordMap | | public class KeywordMap (Code) | | A KeywordMap is similar to a hashtable in that it maps keys
to values. However, the `keys' are Swing segments. This allows lookups of
text substrings without the overhead of creating a new string object.
This class is used by CTokenMarker to map keywords to ids.
