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.
 
BufferRenderGLoperator= (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.

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 4729 of file opencl.hpp.

◆ BufferRenderGL() [2/3]

cl::BufferRenderGL::BufferRenderGL ( )
inline

Default constructor - initializes to nullptr.

Definition at line 4749 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
retainObjectwill cause the constructor to retain its cl object. Defaults to false to maintain compatibility with earlier versions. See Memory for further details.
