Detailed Description
The Event class implements a feature originally found in the WIN32 API; event notification. Thread synchornization on event notification.
A target thread waits on a resetable Event, and one or more other threads can then signal the waiting thread to resume execution. A timeout can be used to specify a wait duration in milliseconds. The Event class must be reset before it can be used again as a trigger. These event objects use a trigger/reset mechanism and are related to low level conditional variables.
