   workbench.gui.editor.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.
