Detailed Description

An interface class that should be implemented by event handlers which are registered via AP_CorrelatorInterface::subscribe.

Member Typedef Documentation

A smart-pointer type for managing lifetime of event handlers.

All event handlers must be stored in an AP_EventHandlerInterface::ptr_t. A reference is held by the correlator for each subscribed event handler. When the last reference is dropped, the event handler will be deleted.

Constructor & Destructor Documentation

virtual AP_EventHandlerInterface::~AP_EventHandlerInterface ( )
inlinevirtual

Ensure we have a virtual destructor, so that derived class destructors can be correctly called.

Member Function Documentation

virtual void AP_EventHandlerInterface::handleEvent ( const AP_Context ctx,
const char *  event,
const char *  channel 
)
pure virtual

Called for each event sent to a channel to which this event handler is subscribed.

Parameters
