| ↳ | 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.

Fields
Public methods
describeContents
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 0orCONTENTS_FILE_DESCRIPTOR | 
getLutProperties
public LutProperties[] getLutProperties ()
Returns the lut properties of the device.
| Returns | |
|---|---|
| LutProperties[] | This value cannot be null. | 
isCombinationSupported
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.
| 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
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
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
| dest | Parcel: This value cannot benull. | 
| flags | int: Additional flags about how the object should be written.
 May be 0 orParcelable.PARCELABLE_WRITE_RETURN_VALUE.
 Value is either0or a combination ofParcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
