Method Detail

getRegisteredErrorHandlers

public Collection<IPublicationErrorHandler> getRegisteredErrorHandlers()

unsubscribe

public boolean unsubscribe(Object listener)

Description copied from interface: PubSubSupport

Immediately remove all registered message handlers (if any) of the given listener. When this call returns all handlers have effectively been removed and will not receive any messages (provided that running publications (iterators) in other threads have not yet obtained a reference to the listener)

A call to this method passing any object that is not subscribed will not have any effect and is silently ignored.

Specified by:

unsubscribe in interface PubSubSupport<T>

Returns:

true, if the listener was found and successfully removed false otherwise

subscribe

public void subscribe(Object listener)

Description copied from interface: PubSubSupport

Subscribe all handlers of the given listener. Any listener is only subscribed once -> subsequent subscriptions of an already subscribed listener will be silently ignored

Specified by:

subscribe in interface PubSubSupport<T>

addErrorHandler

public final void addErrorHandler(IPublicationErrorHandler handler)

getRuntime

public BusRuntime getRuntime()

Specified by:

getRuntime in interface RuntimeProvider

handlePublicationError
