PerformanceHintManager.Session Class

Definition

A Session represents a group of threads with an inter-related workload such that hints for their performance should be considered as a unit.

Remarks

A Session represents a group of threads with an inter-related workload such that hints for their performance should be considered as a unit. The threads in a given session should be long-lived and not created or destroyed dynamically.

The work duration API can be used with periodic workloads to dynamically adjust thread performance and keep the work on schedule while optimizing the available power budget. When using the work duration API, the starting target duration should be specified while creating the session, but can later be adjusted with #updateTargetWorkDuration(long). While using the work duration API, the client is be expected to call #reportActualWorkDuration(long) each cycle to report the actual time taken to complete to the system.

Any call in this class will change its internal data, so you must do your own thread safety to protect from racing.

All timings should be in SystemClock#uptimeNanos().

Wait()

Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>.

(Inherited from Object)
Wait(Int64, Int32)

Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed.

(Inherited from Object)
Wait(Int64)

Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed.
