Get the tokens in the internal List. WARNING: Adding tokens to this list requires the {@link #Reset()} method to be called in order for them to be made available. Also, this Tokenizer does nothing to protect against {@link java.util.ConcurrentModificationException}s in the case of adds happening while {@link #Next(Lucene.Net.Analysis.Token)} is being called. WARNING: Since this SinkTokenizer can be reset and the cached tokens made available again, do not modify them. Modify clones instead.
