<BODY>
Contains collection implementations that use primitive elements. Currently
the package offers lists of primitive elements that are backed by primitive
arrays, offering substantial memory and performance savings.<p>
There are generally two layers of abstract per primitive list type. The
first layer, implemented by the <Code>Abstract*List</Code> classes, provides
default implementations for all of the <Code>java.util.List</Code> methods
and most of their primitive counterparts. The second layer of abstraction,
implemented by the <Code>Abstract*ArrayList</Code> classes, provides
additional method signatures for manipulating a list that's backed by a
primitive array.<p>
Note that these layers are not provided for <Code>FloatArrayList</Code>,
and that many primitive types are not represented in this package at all;
these inconsistencies may be addressed by a future release.

<body>
<p>
Collections that are based upon primitive
types. Generally these extensions offer memory
and performance improvements over the
<code>Object</code> wrapped alternative.
</p>
<p>
The package provides (or will provide) versions of
the major collections framework interfaces
(<code>Collection</code>, <code>List</code>,
<code>Map</code>, <code>Set</code>) and their
helpers (<code>Iterator</code>, <code>ListIterator</code>,
etc) for each primitive type, and various concrete
implementations of these.
</p>
<p>
Adapters are provided for converting between the
primitive and object based versions of the collections
framework.
