Class CharArrayMap<TValue>

A simple class that stores key s as char[]'s in a hash table. Note that this is not a general purpose class. For example, it cannot remove items from the map, nor does it resize its hash table to be smaller, etc. It is designed to be quick to retrieve items by char[] keys without the necessity of converting to a first.

You must specify the required LuceneVersion compatibility when creating CharArrayMap:

As of 3.1, supplementary characters are properly lowercased.

Before 3.1 supplementary characters could not be lowercased correctly due to the lack of Unicode 4 support in JDK 1.4. To use instances of CharArrayMap with the behavior before Lucene 3.1 pass a LuceneVersion < 3.1 to the constructors.
