Detailed Description

The Event class is a unicast message directed at all modules.

When the class is properly instantiated it may be sent to all modules using the Send() method, which will trigger the OnEvent method in all modules passing the object as its parameter.

Constructor & Destructor Documentation

Event::Event (  char *  anydata, Module *  src, std::string  eventid )

Create a new Event. Definition at line 269 of file modules.cpp. : data(anydata), source(src), id(eventid) { };

Member Function Documentation

char * Event::GetData (   )

Get the Event data. Definition at line 271 of file modules.cpp. References data. { return this->data; }

std::string Event::GetEventID (   )

Get the event ID. Use this to determine the event type for safe casting of the data Definition at line 287 of file modules.cpp. References id. { return this->id; }

Module * Event::GetSource (   )

Get the event Source. Definition at line 276 of file modules.cpp. References source. { return this->source; }

char * Event::Send (   )  [virtual]

Send the Event. The return result of an Event::Send() will always be NULL as no replies are expected. Implements ModuleMessage. Definition at line 281 of file modules.cpp. References FOREACH_MOD. { FOREACH_MOD OnEvent(this); return NULL; }

Member Data Documentation

char* Event::data [protected]

This member holds a pointer to arbitary data set by the emitter of the message. Definition at line 199 of file modules.h. Referenced by GetData().

std::string Event::id [protected]

The event identifier. This is arbitary text which should be used to distinguish one type of event from another. Definition at line 208 of file modules.h. Referenced by GetEventID().

Module* Event::source [protected]

This is a pointer to the sender of the message, which can be used to directly trigger events, or to create a reply. Definition at line 203 of file modules.h. Referenced by GetSource().
