public boolean implies(Permission p)
Checks if this MBeanServerPermission object "implies" the specified permission.

- p is an instance of MBeanServerPermission,
- p's target names are a subset of this object's target names
The createMBeanServer
permission implies the newMBeanServer
permission.

in classBasicPermission
- Parameters:
-
p
- the permission to check against. - Returns:
- true if the specified permission is implied by this object, false if not.
equals
public boolean equals(Object obj)

- Overrides:
-
equals
in classBasicPermission
- Parameters:
-
obj
- the object we are testing for equality with this object. - Returns:
