SurfaceControl
class SurfaceControl : Parcelable
Handle to an on-screen Surface managed by the system compositor. The SurfaceControl is a combination of a buffer source, and metadata about how to display the buffers. By constructing a Surface from this SurfaceControl you can submit buffers to be composited. Using SurfaceControl.Transaction you can manipulate various properties of how the buffer will be displayed on-screen. SurfaceControl's are arranged into a scene-graph like hierarchy, and as such any SurfaceControl may have a parent. Geometric properties like transform, crop, and Z-ordering will be inherited from the parent, as if the child were content in the parents buffer stream.
Summary
Nested classes

Builder class for SurfaceControl objects.

An atomic set of changes to a set of SurfaceControl.

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: 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)". Some implementations may want to release resources at this point.

Public methods
describeContents
fun describeContents(): Int
isValid
fun isValid(): Boolean
Check whether this instance points to a valid layer with the system-compositor. For example this may be false if construction failed, or the layer was released (release).
| Return |
Boolean |
Whether this SurfaceControl is valid. |
readFromParcel
fun readFromParcel(in: Parcel!): Unit
release
fun release(): Unit
Release the local reference to the server-side surface. The surface may continue to exist on-screen as long as its parent continues to exist. To explicitly remove a surface from the screen use Transaction#reparent with a null-parent. After release, isValid will return false and other methods will throw an exception. Always call release() when you're done with a SurfaceControl.
toString
fun toString(): String
| Return |
String |
a string representation of the object. |
writeToParcel
fun writeToParcel(
dest: Parcel!,
flags: Int
): Unit
