public abstract class MBeanServerChecker
An object of this class implements the MBeanServer interface and, for each of its methods, calls an appropriate checking method and then forwards the request to a wrapped MBeanServer object. The checking method may throw a RuntimeException if the operation is not allowed; in this case the request is not forwarded to the wrapped object.
A typical use of this class is to insert it between a connector server
such as the HTTP connector and the MBeanServer with which the connector
is associated. Requests from the connector client can then be filtered
and those operations that are not allowed, or not allowed in a particular
context, can be rejected by throwing a SecurityException
in the corresponding check*
method.
A checking method can obtain the OperationContext
associated with the request being handled, if there is one, by
calling getOperationContext()
.
This is an abstract class, because in its implementation none of the checking methods does anything. To be useful, it must be subclassed and at least one of the checking methods overridden to do some checking. Some or all of the MBeanServer methods may also be overridden, for instance if the default checking behavior is inappropriate.
In effect, three levels of checking are possible:
checkAny
so that it applies
some restriction to every operation, or so that it consults the
methodName
parameter to apply restrictions to particular
operations.check*
methods to
apply restrictions to certain classes of methods. Again, the
methodName
parameter is available to refine these
restrictions by applying them only to particular operations.MBeanServer
interface itself. These methods are called with exactly the same
parameters as they will have in the real MBeanServer, so decisions can
be based on complete information. If an operation is accepted, the
overriding method should call super.methodName
to
forward it to the real MBeanServer.The documentation of the individual check*
methods describes
what the value of the methodName
parameter may be. Future
versions of this class may extend these possible values to allow for new
methods in the MBeanServer
interface.
