## Class KeywordMap

- Object
- - KeywordMap

-     public class KeywordMap
      extends Object

  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.

    `byte` | `lookup(Segment text, int offset, int length, boolean paren)` Looks up a key.
    `static boolean` | `regionMatches(boolean ignoreCase, Segment text, int offset, char[] match)` Checks if a subregion of a `Segment` is equal to a character array.
    `void` | `setIgnoreCase(boolean ignoreCase)` Sets if the keyword map should be case insensitive.
