mrpt::system::mrptEvent Class Reference

Detailed Description

The basic event type for the observer-observable pattern in MRPT.

You can sub-class this base class to create custom event types, then tell between them in runtime with isOfType<T>(), for example:

if (e.isOfType<mrptEventOnDestroy>())
{
  const mrptEventOnDestroy* ev = e.getAs<mrptEventOnDestroy>();
  ev-> ...
}
