Class VariableY

java.lang.Object
  org.norther.tammi.core.rt.VariableX
      org.norther.tammi.core.rt.VariableY

All Implemented Interfaces:

Serializable, Cloneable, DynamicMBean, MBeanRegistration, NotificationBroadcaster, NotificationEmitter, Traceable, Identifiable, NamePattern, ReferableMBean, Variable

Direct Known Subclasses:

VariableZ

public class VariableY
extends VariableX
implements NamePattern, NotificationEmitter

An extended Variable implementation supporting a fixed set of dynamic attributes only. VariableY implements NotificationEmitter, which allows its use with handles. The meta-data is locked and shared with other instances of the same virtual type by default making the memory footprint smaller.

Exception

postDeregister

public void postDeregister()

Specified by:

postDeregister in interface MBeanRegistration

Overrides:

postDeregister in class VariableX

getMBean

public MBeanReference getMBean()

Description copied from interface: ReferableMBean

Gets a reference to the MBean.

getMBean in interface ReferableMBean

Overrides:

getMBean in class VariableX

Returns:

a reference to the MBean.

getCanonicalName

public String getCanonicalName()

Description copied from interface: Identifiable

Gets the canonical object name of the MBean as a string.

Specified by:

getCanonicalName in interface Identifiable

Overrides:

getCanonicalName in class VariableX
