Wrapper
isWrapperFor
on the wrapped object. If this does not implement the interface and
is not a wrapper, return false. This method should be implemented as a low-cost operation
compared to unwrap
so that callers can use this method to avoid expensive
unwrap
calls that may fail. If this method returns true then calling unwrap
with the same argument should succeed.isWrapperFor

Wrapper
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
IllegalArgumentException
is thrown.
