Detailed Description

A cooperatively executed task managed by one or more instances of execution_unit.

Note that this class is meant as mixin for reference counted object, i.e., the subclass is required to inherit from ref_counted at some point.

Member Enumeration Documentation

Denotes common subtypes of resumable.

Enumerator
unspecified	Identifies non-actors or blocking actors.
scheduled_actor	Identifies event-based, cooperatively scheduled actors.
io_actor	Identifies broker, i.e., actors performing I/O.
function_object	Identifies tasks, usually one-shot callbacks.

virtual subtype_t caf::resumable::subtype ( ) const

virtual

Returns a subtype hint for this object.

This allows an execution unit to limit processing to a specific set of resumables and delegate other subtypes to dedicated workers.
