|
An EventStreamPlayer is used by link::Classes/Event:: based Patterns.
|
|
|
|
The EventStreamPlayer holds a stream which returns a series of Events, and a protoEvent. At each call to next, it copies the protoEvent, passes that to the stream, and calls strong::play:: on the link::Classes/Event:: returned.
|
|
|
|
For more on EventStreamPlayer see link::Tutorials/Streams-Patterns-Events4::
|
|
|
|
EventStreamPlayer uses the same control methods and status notifications as link::Classes/Task::.

You do not explicitly create an EventStreamPlayers, they are created for you when you call link::Classes/Pattern#-play::.
