@descr It try to close the given resource first.
|
|
Delegating of the ownership can be influenced from
|
|
outside. If closing isnt possible (because the
|
|
needed interface isnt available) dispose() is tried instead.
|
|
Al possible exception are handled inside.
|
|
So the user of this method has to look for the return value only.
|
|
|
|
@attention The given resource will not be cleared.
|
|
But later using of it can produce an exception!
