Class JEditKeywordMap  

java.lang.Object
  com.memoire.jedit.JEditKeywordMap

---

public class JEditKeywordMap

extends java.lang.Object

A JEditKeywordMap 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 JEditCTokenMarker to map keywords to ids.
