Overview

Internals

Core entity is Continuated which provide iteratee-like structure for reading and writing. Instance of Continuated represent one step of computations and leave in queue inside ChannelProcessor or ChannelActor Selector transform Continuated to executed exclusive with each other within one selector. Also we have IdleDetector which determinate idle selectors and activer appropriative actions.

    this is message wich send to ChannelActor, when we know, that channel is closed.

    this is message wich send to ChannelActor, when we know, that channel is closed. In such case, we don't konw: is actor stopped or not, So, we say this message (instead read) and wait for reply. If reply is not received within given timeout: think that channel is-dead.
