Summary

Public constructors

Builder()
Builder(GpuHeadroomParams params)

Returns a new builder with the same values as this object.

Public methods

GpuHeadroomParams build()

Builds the GpuHeadroomParams object.

GpuHeadroomParams.Builder setCalculationType(int calculationType)

Sets the headroom calculation type.

GpuHeadroomParams.Builder setCalculationWindowMillis(int windowMillis)

Sets the headroom calculation window size in milliseconds.

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

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

final void wait(long timeoutMillis)

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

final void wait()

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

public Builder ()

Builder

public Builder (GpuHeadroomParams params)

Returns a new builder with the same values as this object.

Parameters
params GpuHeadroomParams: This value cannot be null.

Public methods

build

public GpuHeadroomParams build ()

Builds the GpuHeadroomParams object.

Returns
GpuHeadroomParams This value cannot be null.

setCalculationType

public GpuHeadroomParams.Builder setCalculationType (int calculationType)

Sets the headroom calculation type.

Returns
GpuHeadroomParams.Builder This value cannot be null.

Throws
IllegalArgumentException if the type is invalid.

setCalculationWindowMillis

public GpuHeadroomParams.Builder setCalculationWindowMillis (int windowMillis)

Sets the headroom calculation window size in milliseconds.

Parameters
windowMillis int: the window size in milliseconds ranges from SystemHealthManager.getGpuHeadroomCalculationWindowRange(). The smaller the window size, the larger fluctuation in the headroom value should be expected. The default value can be retrieved from the GpuHeadroomParams.getCalculationWindowMillis. The device will try to use the closest feasible window size to this param. Value is 1 or greater

Returns
GpuHeadroomParams.Builder This value cannot be null.

Throws
IllegalArgumentException if the window is invalid.
