Method Detail

constructDispatchingHandlerState

protected DispatchingHandlerState constructDispatchingHandlerState()
                                                            throws IfsException

Description copied from class: DispatchingHandler

Constructs the DispatchingHandlerState.

This is typically overridden by subclasses that wish to add custom dispatching logic.

Overrides:

constructDispatchingHandlerState in class DispatchingHandler

Returns:

a newly constructed state instance

Throws:

IfsException - if the opertation fails

processEvent

protected void processEvent(LibrarySession session,
                            AuditEvent event,
                            DispatchedEvent de)
                     throws IfsException

Description copied from class: DispatchingHandler

Low-level processing of an event.

Specified by:

processEvent in class DispatchingHandler

Parameters:

session - the session Context to use for processing

event - the event to process

de - the associated DispatchedEvent

Throws:

IfsException - if the operation fails

reallyProcessTheEvent

protected void reallyProcessTheEvent(LibrarySession session,
                                     AuditEvent event,
                                     DispatchedEvent de)
                              throws IfsException

Throws:

IfsException
