An Event object represents an event instance.
Must be created using com::apama::event::createEvent Must be destroyed using com::apama::event::deleteEvent
Event is not copiable
virtual const char* com::apama::event::Event::getChannel |
( |
| ) |
const |
|
pure virtual |
Retrieve the event's channel.
This currently only has meaning for events which have been sourced from the correlator, in which case it is set to the name of the channel the event was emitted from, or "" (the empty string) for the wildcard channel.
- Returns
- The channel of the event, encoded in UTF-8.
virtual const char* com::apama::event::Event::getText |
( |
| ) |
const |
|
pure virtual |
Retrieve the event's type and its contents as a string.
- Returns
- C style string with the event's textual representation. Note that these strings should be encoded in UTF-8.
virtual double com::apama::event::Event::getTime |
( |
| ) |
const |
|
pure virtual |
Retrieve the event's timestamp.
This timestamp currently only has meaning for events which have been sourced from the correlator, in which case it is set to the correlator time at which it was created, or the value it was set to explicitly by code running within the correlator.
- Returns
- the timestamp of the event, in floating point seconds since the Unix epoch.
