## Detailed Description

Class interface for cl_event.

Note
  Copies of these objects are shallow, meaning that the copy will refer to the same underlying cl_event as the original. For details, see clRetainEvent() and clReleaseEvent().

## Constructor & Destructor Documentation

## Event() [1/2]

cl::Event::Event | ( |  | ) |

inline

Default constructor - initializes to nullptr.

Definition at line 3703 of file opencl.hpp.

## Event() [2/2]

cl::Event::Event | ( | const cl_event & | event,
|  | bool | retainObject = false )

inline explicit

Constructor from cl_event - takes ownership.

Parameters

  retainObject | will cause the constructor to retain its cl object. Defaults to false to maintain compatibility with earlier versions. This effectively transfers ownership of a refcount on the cl_event into the new Event object.

Definition at line 3713 of file opencl.hpp.

## Member Function Documentation

## getInfo() [1/2]

template<typename T>

cl_int cl::Event::getInfo | ( | cl_event_info | name,
|  | T * | param ) const

inline

Wrapper for clGetEventInfo().

Definition at line 3729 of file opencl.hpp.

## getInfo() [2/2]

template<cl_event_info name>

detail::param_traits< detail::cl_event_info, name >::param_type cl::Event::getInfo | ( | cl_int * | err = nullptr | ) | const

inline

Wrapper for clGetEventInfo() that returns by value.

Definition at line 3739 of file opencl.hpp.

## getProfilingInfo() [1/2]

template<cl_profiling_info name>

detail::param_traits< detail::cl_profiling_info, name >::param_type cl::Event::getProfilingInfo | ( | cl_int * | err = nullptr | ) | const

inline

Wrapper for clGetEventProfilingInfo() that returns by value.

Definition at line 3762 of file opencl.hpp.

## getProfilingInfo() [2/2]

template<typename T>

cl_int cl::Event::getProfilingInfo | ( | cl_profiling_info | name,
|  | T * | param ) const

inline

Wrapper for clGetEventProfilingInfo().

Definition at line 3752 of file opencl.hpp.

## operator=()

Event & cl::Event::operator= | ( | const cl_event & | rhs | ) |

inline

Assignment operator from cl_event - takes ownership.

This effectively transfers ownership of a refcount on the rhs and calls clReleaseEvent() on the value previously held by this instance.

Definition at line 3721 of file opencl.hpp.

## setCallback()

cl_int cl::Event::setCallback | ( | cl_int | type,
|  | void(CL_CALLBACK *pfn_notify)(cl_event, cl_int, void *) | ,
|  | void * | user_data = nullptr )

inline

Registers a user callback function for a specific command execution status.

Wraps clSetEventCallback().

Definition at line 3789 of file opencl.hpp.

## wait()

cl_int cl::Event::wait | ( |  | ) | const

inline

Blocks the calling thread until this event completes.

Wraps clWaitForEvents().

Definition at line 3777 of file opencl.hpp.

## waitForEvents()

cl_int cl::Event::waitForEvents | ( | const vector< Event > & | events | ) |

inline static

Blocks the calling thread until every event specified is complete.

Wraps clWaitForEvents().

Definition at line 3809 of file opencl.hpp.
