The target parameter is an object that is not of the same type as the current permission object. |
The current permission object is a subset of the specified permission object if the current permission object specifies a set of operations that is wholly contained by the specified permission object.
For example, a permission that represents access to C:\example.txt is a subset of a permission that represents access to C:\. If this method returns true, the current permission object represents no more access to the protected resource than does the specified permission object.
