Scheduler::ExecutionCtx Class Reference

#include "vault/gear/scheduler.hpp"

Description

Remarks

when due, the scheduled Activities are performed within the Activity-Language execution environment; some aspects of Activity activation however require external functionality, which — for the purpose of language definition — was abstracted as Execution-context. The implementation of these binding functions fills in relevant external effects and is in fact supplied by the implementation internals of the scheduler itself.

Constructor & Destructor Documentation

ExecutionCtx()

ExecutionCtx ( Scheduler &  self, ActivationEvent  toDispatch  )

inline

Definition at line 446 of file scheduler.hpp.

Member Function Documentation

post()

activity::Proc post ( Time  when, Time  dead, Activity *  chain, ExecutionCtx &  ctx  )

inline

λ-post: enqueue for time-bound execution, within given ExecutionCtx.

Remarks

This function represents an abstracted entrance to scheduling for the ActivityLang and is relevant for recursive forwarding of activations and notifications. The concrete implementation needs some further contextual information, which is passed down here as a nested sub-context.
