Package com.jogamp.opencl

Class CLEvent

java.lang.Object

com.jogamp.opencl.CLObject

com.jogamp.opencl.CLEvent

All Implemented Interfaces:

AutoCloseable, CLResource

Direct Known Subclasses:

CLUserEvent

public class CLEvent
extends CLObject

Event objects can be used for synchronizing command queues, e.g you can wait until a event occurs or they can also be used to capture profiling information that measure execution time of a command. Profiling of OpenCL commands can be enabled by using a CLCommandQueue created with CLCommandQueue.Mode.PROFILING_MODE.
