Inheritance diagram for cl::BufferRenderGL:

## Public Member Functions
| BufferRenderGL (const Context &context, cl_mem_flags flags, cl_GLuint bufobj, cl_int *err=nullptr)
| Constructs a BufferRenderGL in a specified context, from a given GL Renderbuffer.
| BufferRenderGL ()
| Default constructor - initializes to nullptr.
| BufferRenderGL (const cl_mem &buffer, bool retainObject=false)
| Constructor from cl_mem - takes ownership.
BufferRenderGL & | operator= (const cl_mem &rhs)
| Assignment from cl_mem - performs shallow copy.
cl_int | getObjectInfo (cl_gl_object_type *type, cl_GLuint *gl_object_name)
| Wrapper for clGetGLObjectInfo().
Public Member Functions inherited from cl::Buffer
| Buffer (const Context &context, cl_mem_flags flags, size_type size, void *host_ptr=nullptr, cl_int *err=nullptr)
| Constructs a Buffer in a specified context.
| Buffer (const Context &context, const vector< cl_mem_properties > &properties, cl_mem_flags flags, size_type size, void *host_ptr=nullptr, cl_int *err=nullptr)
| Constructs a Buffer in a specified context and with specified properties.
| Buffer (cl_mem_flags flags, size_type size, void *host_ptr=nullptr, cl_int *err=nullptr)
| Constructs a Buffer in the default context.
| Buffer (const vector< cl_mem_properties > &properties, cl_mem_flags flags, size_type size, void *host_ptr=nullptr, cl_int *err=nullptr)
| Constructs a Buffer in the default context and with specified properties.
template<typename IteratorType >
| Buffer (IteratorType startIterator, IteratorType endIterator, bool readOnly, bool useHostPtr=false, cl_int *err=nullptr)
| Construct a Buffer from a host container via iterators. IteratorType must be random access. If useHostPtr is specified iterators must represent contiguous data.
template<typename IteratorType >
| Buffer (const Context &context, IteratorType startIterator, IteratorType endIterator, bool readOnly, bool useHostPtr=false, cl_int *err=nullptr)
| Construct a Buffer from a host container via iterators using a specified context. IteratorType must be random access. If useHostPtr is specified iterators must represent contiguous data.
template<typename IteratorType >
| Buffer (const CommandQueue &queue, IteratorType startIterator, IteratorType endIterator, bool readOnly, bool useHostPtr=false, cl_int *err=nullptr)
| Construct a Buffer from a host container via iterators using a specified queue. If useHostPtr is specified iterators must be random access.
| Buffer ()
| Default constructor - initializes to nullptr.
| Buffer (const cl_mem &buffer, bool retainObject=false)
| Constructor from cl_mem - takes ownership.
Buffer & | operator= (const cl_mem &rhs)
| Assignment from cl_mem - performs shallow copy.
Buffer | createSubBuffer (cl_mem_flags flags, cl_buffer_create_type buffer_create_type, const void *buffer_create_info, cl_int *err=nullptr)
| Creates a new buffer object from this.
Public Member Functions inherited from cl::Memory
| Memory ()
| Default constructor - initializes to nullptr.
| Memory (const cl_mem &memory, bool retainObject)
| Constructor from cl_mem - takes ownership.
Memory & | operator= (const cl_mem &rhs)
| Assignment operator from cl_mem - takes ownership.
template<typename T >
cl_int | getInfo (cl_mem_info name, T *param) const
| Wrapper for clGetMemObjectInfo().
template<cl_mem_info name>
detail::param_traits< detail::cl_mem_info, name >::param_type | getInfo (cl_int *err=nullptr) const
| Wrapper for clGetMemObjectInfo() that returns by value.
cl_int | setDestructorCallback (void(CL_CALLBACK *pfn_notify)(cl_mem, void *), void *user_data=nullptr)
| Registers a callback function to be called when the memory object is no longer needed.

## Constructor & Destructor Documentation

## ◆ BufferRenderGL() [1/3]

cl::BufferRenderGL::BufferRenderGL | ( | const Context & | context,
|  | cl_mem_flags | flags,
|  | cl_GLuint | bufobj,
|  | cl_int * | err = `nullptr`
| ) |  |
| inline

Constructs a BufferRenderGL in a specified context, from a given GL Renderbuffer.

Wraps clCreateFromGLRenderbuffer().

Definition at line 4479 of file opencl.hpp.

## ◆ BufferRenderGL() [2/3]

cl::BufferRenderGL::BufferRenderGL | ( |  | ) |
| inline

Default constructor - initializes to nullptr.

Definition at line 4499 of file opencl.hpp.

## ◆ BufferRenderGL() [3/3]

cl::BufferRenderGL::BufferRenderGL | ( | const cl_mem & | buffer,
|  | bool | retainObject = `false`
| ) |  |
| inlineexplicit

Constructor from cl_mem - takes ownership.

Parameters

  retainObject | will cause the constructor to retain its cl object. Defaults to false to maintain compatibility with earlier versions. See Memory for further details.
