OverlayProperties
class OverlayProperties : Parcelable
| kotlin.Any | |
| ↳ | 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 android.view.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 android.view.SurfaceControl tree is power-efficient and performant.

Public methods
describeContents
fun describeContents(): Int
| Return | |
|---|---|
Int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR |
isCombinationSupported
fun isCombinationSupported(
dataspace: Int,
format: Int
): Boolean
Indicates that hardware composition of a buffer encoded with the provided DataSpace and android.hardware.HardwareBuffer.Format is supported on the device.
| Return | |
|---|---|
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
fun isMixedColorSpacesSupported(): Boolean
Indicates that hardware composition of two or more overlays with different colorspaces is supported on the device.
| Return | |
|---|---|
Boolean |
True if the device can support mixed colorspaces efficiently, false if GPU composition fallback is otherwise required. |
writeToParcel
fun writeToParcel(
dest: Parcel,
flags: Int
): Unit
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_WRITE_RETURN_VALUE. Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
