Method Detail

initInternal

protected void initInternal()
                     throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes implement this method to perform any instance initialisation required.

Specified by:

initInternal in class LifecycleBase

Throws:

LifecycleException - If the initialisation fails

destroyInternal

protected void destroyInternal()
                        throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes implement this method to perform any instance destruction required.

Specified by:

destroyInternal in class LifecycleBase

Throws:

LifecycleException - If the destruction fails

setDomain

public final void setDomain(java.lang.String domain)

Description copied from interface: JmxEnabled

Specify the domain under which this component should be registered. Used with components that cannot (easily) navigate the component hierarchy to determine the correct domain to use.

Specified by:

setDomain in interface JmxEnabled

Parameters:

domain - The name of the domain under which this component should be registered

getDomain

public final java.lang.String getDomain()

Specified by:

getDomain in interface JmxEnabled

Returns:

the domain under which this component will be / has been registered.

getDomainInternal

protected abstract java.lang.String getDomainInternal()

Method implemented by sub-classes to identify the domain in which MBeans should be registered.

Returns:

The name of the domain to use to register MBeans.

getObjectName

public final javax.management.ObjectName getObjectName()

Specified by:

getObjectName in interface JmxEnabled

Returns:

the name under which this component has been registered with JMX.

getObjectNameKeyProperties

protected abstract java.lang.String getObjectNameKeyProperties()

Allow sub-classes to specify the key properties component of the ObjectName that will be used to register this component.

Returns:

The string representation of the key properties component of the desired ObjectName

register

protected final javax.management.ObjectName register(java.lang.Object obj,
                                                     java.lang.String objectNameKeyProperties)

Utility method to enable sub-classes to easily register additional components that don't implement JmxEnabled with an MBean server.
Note: This method should only be used once initInternal() has been called and before destroyInternal() has been called.

Parameters:

obj - The object the register

objectNameKeyProperties - The key properties component of the object name to use to register the object

Returns:

The name used to register the object

unregister

protected final void unregister(java.lang.String objectNameKeyProperties)

Utility method to enable sub-classes to easily unregister additional components that don't implement JmxEnabled with an MBean server.
Note: This method should only be used once initInternal() has been called and before destroyInternal() has been called.

Parameters:

objectNameKeyProperties - The key properties component of the object name to use to unregister the object

unregister

protected final void unregister(javax.management.ObjectName on)

Utility method to enable sub-classes to easily unregister additional components that don't implement JmxEnabled with an MBean server.
Note: This method should only be used once initInternal() has been called and before destroyInternal() has been called.

Parameters:

on - The name of the component to unregister

postDeregister

public final void postDeregister()

Not used - NOOP.

Specified by:

postDeregister in interface javax.management.MBeanRegistration

postRegister

public final void postRegister(java.lang.Boolean registrationDone)

Not used - NOOP.

Specified by:

postRegister in interface javax.management.MBeanRegistration

preDeregister

public final void preDeregister()
                         throws java.lang.Exception

Not used - NOOP.

Specified by:

preDeregister in interface javax.management.MBeanRegistration

Throws:

java.lang.Exception

preRegister

public final javax.management.ObjectName preRegister(javax.management.MBeanServer server,
                                                     javax.management.ObjectName name)
                                              throws java.lang.Exception

Specified by:

preRegister in interface javax.management.MBeanRegistration

Throws:
