Description copied from interface: Wrapper

Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an OntoDriverException is thrown.

Specified by:

unwrap in interface Wrapper

Type Parameters:

T - The type of the class modeled by this Class object

Parameters:

cls - The type of the required result

Returns:

An object implementing the interface

Throws:

OntoDriverException - If no matching object is found
