Detailed Description

A TaskRunner allows scheduling of tasks. The TaskRunner may still be used to post tasks after the isolate gets destructed, but these tasks may not get executed anymore. All tasks posted to a given TaskRunner will be invoked in sequence. Tasks can be posted from any thread.

Member Function Documentation

IdleTasksEnabled()

virtual bool IdleTasksEnabled ( )

pure virtual

Returns true if idle tasks are enabled for this TaskRunner.

NonNestableDelayedTasksEnabled()

virtual bool NonNestableDelayedTasksEnabled ( ) const

inlinevirtual

Returns true if non-nestable delayed tasks are enabled for this TaskRunner.

Definition at line 107 of file v8-platform.h.

NonNestableTasksEnabled()

virtual bool NonNestableTasksEnabled ( ) const

inlinevirtual

Returns true if non-nestable tasks are enabled for this TaskRunner.

Definition at line 102 of file v8-platform.h.

PostDelayedTask()

virtual void PostDelayedTask ( std::unique_ptr< Task >  task, double  delay_in_seconds  )

pure virtual

Schedules a task to be invoked by this TaskRunner. The task is scheduled after the given number of seconds |delay_in_seconds|. The TaskRunner implementation takes ownership of |task|.

PostIdleTask()

virtual void PostIdleTask ( std::unique_ptr< IdleTask >  task )

pure virtual

Schedules an idle task to be invoked by this TaskRunner. The task is scheduled when the embedder is idle. Requires that |TaskRunner::IdleTasksEnabled()| is true. Idle tasks may be reordered relative to other task types and may be starved for an arbitrarily long time if no idle time is available. The TaskRunner implementation takes ownership of |task|.

PostNonNestableDelayedTask()

virtual void PostNonNestableDelayedTask ( std::unique_ptr< Task >  task, double  delay_in_seconds  )

inlinevirtual

Schedules a task to be invoked by this TaskRunner. The task is scheduled after the given number of seconds |delay_in_seconds|. The TaskRunner implementation takes ownership of |task|. The |task| cannot be nested within other task executions.

Requires that |TaskRunner::NonNestableDelayedTasksEnabled()| is true.

Definition at line 81 of file v8-platform.h.

PostNonNestableTask()

virtual void PostNonNestableTask ( std::unique_ptr< Task >  task )

inlinevirtual

Schedules a task to be invoked by this TaskRunner. The TaskRunner implementation takes ownership of |task|. The |task| cannot be nested within other task executions.

Requires that |TaskRunner::NonNestableTasksEnabled()| is true.

Definition at line 63 of file v8-platform.h.

PostTask()

virtual void PostTask ( std::unique_ptr< Task >  task )

pure virtual

Schedules a task to be invoked by this TaskRunner. The TaskRunner implementation takes ownership of |task|.
