init

public void init()

propertiesChange

public void propertiesChange(JProperties properties)

Description copied from interface: JPropertiesListener

Invoked after properties have been modified in JCMS and save on disk.

You cannot alter the value received in parameters.

Specified by:

propertiesChange in interface JPropertiesListener

Parameters:

properties - the properties which have been modified (may not contain all JCMS properties)

initBeforeStoreLoad

public void initBeforeStoreLoad()

Specified by:

initBeforeStoreLoad in class ChannelListener

Throws:

Exception - any exception you may want to throw if a problem occurs needing to interrupt JCMS startup.

initAfterStoreLoad

public void initAfterStoreLoad()
                        throws Exception

Description copied from class: ChannelListener

Called just after the store has been loaded and the channel has been initialized. If for any reason you want to interrupt JCMS startup, you can throw an exception. The exception's message will be displayed in JCMS status page (to any user!).

Specified by:

initAfterStoreLoad in class ChannelListener

Throws:

Exception - any exception you may want to throw if a problem occurs needing to interrupt JCMS startup.

public void handleFinalize()

Description copied from class: ChannelListener

Called when the channel is finalized

Specified by:

handleFinalize in class ChannelListener
