When used to wrap a non-null NIO buffer object, this class will create a read-only view of the wrapped NIO buffer, and will call <code>rewind</code> on the read-only view, so that elements 0 through <code>buffer.limit()-1</code> will be available internally. <p> NOTE: Use of this class requires version 1.4 of the Java<sup><font size="-2">TM</font></sup> 2 Platform. Any attempt to access this class on an earlier version of the Java 2 Platform will fail with a NoClassDefFoundError.
