Class APPLESync

java.lang.Object

org.lwjgl.opengles.APPLESync

public class APPLESync
extends java.lang.Object

Native bindings to the APPLE_sync extension.

This extension introduces the concept of "sync objects". Sync objects are a synchronization primitive - a representation of events whose completion status can be tested or waited upon. One specific type of sync object, the "fence sync object", is supported in this extension, and additional types can easily be added in the future.

Fence sync objects have corresponding fences, which are inserted into the OpenGL command stream at the time the sync object is created. A sync object can be queried for a given condition. The only condition supported for fence sync objects is completion of the corresponding fence command. Fence completion allows applications to request a partial Finish, wherein all commands prior to the fence will be forced to complete before control is returned to the calling process.

These new mechanisms allow for synchronization between the host CPU and the GPU, which may be accessing the same resources (typically memory), as well as between multiple GL contexts bound to multiple threads in the host CPU.

Requires GLES 2.0.
