public final class FastCharStream

extends Object

Modified version of org.apache.lucene.queryParser.FastCharStream based on a String input.

An efficient implementation of JavaCC's CharStream interface.

Note that this does not do line-number counting, but instead keeps track of the character position of the token in the input, as required by Lucene's Token API.
