Method Detail

stateChanged

public void stateChanged(ConfiguredObject<?> object,
                         State oldState,
                         State newState)

Description copied from interface: ConfigurationChangeListener

Inform the listener that the passed object has changed state

Specified by:

stateChanged in interface ConfigurationChangeListener

Parameters:

object - the object whose state has changed

oldState - the state prior to the change

newState - the state after the change

childAdded

public void childAdded(ConfiguredObject<?> object,
                       ConfiguredObject<?> child)

Specified by:

childAdded in interface ConfigurationChangeListener

childRemoved

public void childRemoved(ConfiguredObject<?> object,
                         ConfiguredObject<?> child)

Specified by:

childRemoved in interface ConfigurationChangeListener

attributeSet

public void attributeSet(ConfiguredObject<?> object,
                         String attributeName,
                         Object oldAttributeValue,
                         Object newAttributeValue)

Specified by:

attributeSet in interface ConfigurationChangeListener

bulkChangeStart

public void bulkChangeStart(ConfiguredObject<?> object)

Description copied from interface: ConfigurationChangeListener

Inform the listener that several attributes of an object are about to change. The listener may choose to defer any action in attributeSet until bulkChangeEnd is called. There should not be multiple calls to bulkChangeStart without matching bulkChangeEnd calls in between. There should be no calls to attributeSet for objects other than the one passed as an argument until bulkChangeEnd is called. There should be no call to childRemove between bulkChangeStart/-End calls.

Specified by:

bulkChangeStart in interface ConfigurationChangeListener

Parameters:

object - the object whose state is about to change

See Also:

ConfigurationChangeListener.bulkChangeEnd(org.apache.qpid.server.model.ConfiguredObject<?>)

bulkChangeEnd

public void bulkChangeEnd(ConfiguredObject<?> object)

Description copied from interface: ConfigurationChangeListener

Inform the listener that the changes announced by bulkChangeStart are complete. The listener who has chosen to defer any action in attributeSet after bulkChangeStart was called should now act on those changes. A call to bulkChangeEnd without a prior matching call to bulkChangeStart should have no effect.

Specified by:

bulkChangeEnd in interface ConfigurationChangeListener

Parameters:

object - the object whose state has changed

ConfigurationChangeListener.bulkChangeStart(org.apache.qpid.server.model.ConfiguredObject<?>)
