aoqi@0:  *  Wrap objects to enable unchecked exceptions to be caught and handled.
aoqi@0:  *
aoqi@0:  *  For each method, exceptions are handled as follows:
aoqi@0:  *  <ul>
aoqi@0:  *  <li>Checked exceptions are left alone and propogate upwards in the
aoqi@0:  *      obvious way, since they are an expected aspect of the method's
aoqi@0:  *      specification.
aoqi@0:  *  <li>Unchecked exceptions which have already been caught and wrapped in
aoqi@0:  *      ClientCodeException are left alone to continue propogating upwards.
aoqi@0:  *  <li>All other unchecked exceptions (i.e. subtypes of RuntimeException
aoqi@0:  *      and Error) and caught, and rethrown as a ClientCodeException with
aoqi@0:  *      its cause set to the original exception.
aoqi@0:  *  </ul>
aoqi@0:  *
aoqi@0:  *  The intent is that ClientCodeException can be caught at an appropriate point
aoqi@0:  *  in the program and can be distinguished from any unanticipated unchecked
aoqi@0:  *  exceptions arising in the main body of the code (i.e. bugs.) When the
aoqi@0:  *  ClientCodeException has been caught, either a suitable message can be
aoqi@0:  *  generated, or if appropriate, the original cause can be rethrown.
aoqi@0:  *
aoqi@0:  *  <p><b>This is NOT part of any supported API.
aoqi@0:  *  If you write code that depends on this, you do so at your own risk.
aoqi@0:  *  This code and its internal interfaces are subject to change or
aoqi@0:  *  deletion without notice.</b>
