class:: EventStreamPlayer
summary:: two streams combined by a binary operator
related:: Classes/Event, Classes/Pbind
categories:: Streams-Patterns-Events
description::
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::.
ClassMethods::
method::new
note::
You do not explicitly create an EventStreamPlayers, they are created for you when you call link::Classes/Pattern#-play::.
::
InstanceMethods::

method::start
Restart the task from the beginning.
method::resume
Resume the task where it left off.

method::stop
Stop playing now. (Pause and stop have the same implementation.)
