public class StandardMBeanSupport extends MBeanSupport<Method> {
Construct a Standard MBean that wraps the given resource using the
given Standard MBean interface.
Params: - resource – the underlying resource for the new MBean.
- mbeanInterfaceType – the class or interface to be used to determine the MBean's management interface. An interface if this is a classic Standard MBean; a class if this is a
@ManagedResource
.
Type parameters: - <T> – a type parameter that allows the compiler to check that
resource
implements mbeanInterfaceType
, provided that mbeanInterfaceType
is a class constant like SomeMBean.class
.
Throws: - IllegalArgumentException – if
resource
is null or if it does not implement the class mbeanInterfaceType
or if that class is not a valid Standard MBean interface.
