OverlayProperties

Kotlin |Java

public final class OverlayProperties
extends Object implements Parcelable

java.lang.Object
↳	android.hardware.OverlayProperties

---

Provides supported overlay properties of the device.

Hardware overlay is a technique to composite different buffers directly to the screen using display hardware rather than the GPU. The system compositor is able to assign any content managed by a SurfaceControl onto a hardware overlay if possible. Applications may be interested in the display hardware capabilities exposed by this class as a hint to determine if their SurfaceControl tree is power-efficient and performant.

Summary

Inherited constants

From interface android.os.Parcelable int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Fields
public static final Creator<OverlayProperties>	CREATOR

Public methods
int	describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
LutProperties[]	getLutProperties() Returns the lut properties of the device.
boolean	isCombinationSupported(int dataspace, int format) Indicates that hardware composition of a buffer encoded with the provided DataSpace and ERROR(HardwareBuffer.Format/android.hardware.HardwareBuffer.Format HardwareBuffer.Format) is supported on the device.
boolean	isMixedColorSpacesSupported() Indicates that hardware composition of two or more overlays with different colorspaces is supported on the device.
void	writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Inherited methods
From class java.lang.Object 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.
From interface android.os.Parcelable abstract int describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. abstract void writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Fields

CREATOR

Added in API level 35

public static final Creator<OverlayProperties> CREATOR

Public methods

describeContents

Added in API level 35

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getLutProperties

Added in Android Baklava

public LutProperties[] getLutProperties ()

Returns the lut properties of the device.

Returns
LutProperties[]	This value cannot be null.

isCombinationSupported

Added in API level 35

public boolean isCombinationSupported (int dataspace, 
                int format)

Indicates that hardware composition of a buffer encoded with the provided DataSpace and ERROR(HardwareBuffer.Format/android.hardware.HardwareBuffer.Format HardwareBuffer.Format) is supported on the device.

Parameters
dataspace	int: Value is either 0 or a combination of DataSpace.DATASPACE_UNKNOWN, DataSpace.DATASPACE_SCRGB_LINEAR, DataSpace.DATASPACE_SRGB, DataSpace.DATASPACE_SCRGB, DataSpace.DATASPACE_DISPLAY_P3, DataSpace.DATASPACE_BT2020_HLG, DataSpace.DATASPACE_BT2020_PQ, DataSpace.DATASPACE_ADOBE_RGB, DataSpace.DATASPACE_JFIF, DataSpace.DATASPACE_BT601_625, DataSpace.DATASPACE_BT601_525, DataSpace.DATASPACE_BT2020, DataSpace.DATASPACE_BT709, DataSpace.DATASPACE_DCI_P3, and DataSpace.DATASPACE_SRGB_LINEAR
format	int: Value is HardwareBuffer.RGBA_8888, HardwareBuffer.RGBA_FP16, HardwareBuffer.RGBA_1010102, HardwareBuffer.RGBX_8888, HardwareBuffer.RGB_888, HardwareBuffer.RGB_565, HardwareBuffer.BLOB, HardwareBuffer.YCBCR_420_888, HardwareBuffer.D_16, HardwareBuffer.D_24, HardwareBuffer.DS_24UI8, HardwareBuffer.D_FP32, HardwareBuffer.DS_FP32UI8, HardwareBuffer.S_UI8, HardwareBuffer.YCBCR_P010, HardwareBuffer.YCBCR_P210, HardwareBuffer.R_8, HardwareBuffer.R_16, HardwareBuffer.RG_1616, or HardwareBuffer.RGBA_10101010

Returns
boolean	True if the device can support efficiently compositing the content described by the dataspace and format. False if GPU composition fallback is otherwise required.

isMixedColorSpacesSupported

Added in API level 35

public boolean isMixedColorSpacesSupported ()

Indicates that hardware composition of two or more overlays with different colorspaces is supported on the device.

Returns
boolean	True if the device can support mixed colorspaces efficiently, false if GPU composition fallback is otherwise required.

writeToParcel

Added in API level 35

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest	Parcel: This value cannot be null.
flags	int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
