/**
* Wrapper class to make a TIntList conform to the java.util.List API.

* APIs into their Trove primitive analogs.
*
* Note that wrapping and unwrapping primitive values is extremely inefficient. If
* possible, users of this class should override the appropriate methods in this class
* and use a table of canonical values.
