Detailed Description

V8 Platform abstraction layer.

The embedder has to provide an implementation of this interface before initializing the rest of V8.

Member Enumeration Documentation

◆ ExpectedRuntime

enum ExpectedRuntime

This enum is used to indicate whether a task is potentially long running, or causes a long wait. The embedder might want to use this hint to decide whether to execute the task on a dedicated thread.

Member Function Documentation

◆ CallOnBackgroundThread()

virtual void CallOnBackgroundThread	(	Task *	task,
		ExpectedRuntime	expected_runtime
	)

pure virtual

Schedules a task to be invoked on a background thread. |expected_runtime| indicates that the task will run a long time. The Platform implementation takes ownership of |task|. There is no guarantee about order of execution of tasks wrt order of scheduling, nor is there a guarantee about the thread the task will be run on.

◆ CallOnForegroundThread()

virtual void CallOnForegroundThread	(	Isolate *	isolate,
		Task *	task
	)

pure virtual

Schedules a task to be invoked on a foreground thread wrt a specific |isolate|. Tasks posted for the same isolate should be execute in order of scheduling. The definition of "foreground" is opaque to V8.
