Events
Event source that emits events when react, except or unreact is called.
Event source that emits events when react, except or unreact is called.
Emitter is simultaneously an event stream, and an observer.
An event stream that emits events when the underlying mutable object is modified.
An event stream that emits events when the underlying mutable object is modified.
An event with underlying mutable value is emitted whenever the mutable value was potentially mutated. This type of a signal provides a controlled way of manipulating mutable values.
Note:
The underlying mutable object must never be mutated directly by accessing
the value of the signal and changing the mutable object. Instead, the mutate
operation of Events should be used to mutate the underlying mutable object.
Example:
val systemMessages = new Events.Emitter[String] val log = new Events.Mutable(new mutable.ArrayBuffer[String]) val logMutations = systemMessages.mutate(log) { buffer => msg => buffer += msg } systemMessages.react("New message arrived!") // buffer now contains the message
As long as there are no feedback loops in the dataflow graph,
the same thread will never modify the mutable object at the same time.
See the mutate method on Eventss for more information.
Note that mutable event stream never unreacts.
