public interface Protectable

Allows objects to be locked for modification.

When an object is protected, modifications to the object are not allowed. To allow modifications for the object, the enableAccess(Object) or the unprotect(Object) methods must be invoked.

To protect the object after enabling access, invoke the disableAccess() access.

Note that enabling or disabling access only applies to the current thread.
