Detailed Description

GLBufferHandle manages RAII ownership for GL buffer object.

Constructor & Destructor Documentation

GLBufferHandle() [1/4]

kanzi::GLBufferHandle::GLBufferHandle ( )

explicit

Constructs an empty GLBufferHandle which does not own any GL buffer object.

GLBufferHandle() [2/4]

kanzi::GLBufferHandle::GLBufferHandle ( Renderer *  renderer )

explicit

Creates a new GL buffer object with renderer and constructs a GLBufferHandle which owns it.

Parameters

renderer

Renderer

~GLBufferHandle()

kanzi::GLBufferHandle::~GLBufferHandle

(

)

GLBufferHandle() [3/4]

kanzi::GLBufferHandle::GLBufferHandle ( Renderer *  renderer, unsigned int  handle, bool  takeOwnership  )

explicit

Creates a wrapper for pre-existing GL buffer object.

If takeOwnership is true, the GL buffer object is externally managed, and it will not be deleted when the handle is destroyed.

Parameters

renderer	Renderer
handle	Pre-existing GL buffer object name
takeOwnership	Should newly created GLBufferHandle take ownership of the GL buffer object

GLBufferHandle() [4/4]

kanzi::GLBufferHandle::GLBufferHandle ( GLBufferHandle &&  other )

inline

Member Function Documentation

release()

unsigned int kanzi::GLBufferHandle::release

(

)

Releases the ownership of the GL buffer if any.

get() returns 0 after the call.

Returns

Handle to the GL buffer object

operator=()

GLBufferHandle& kanzi::GLBufferHandle::operator= ( GLBufferHandle &&  other )

inline

get()

unsigned int kanzi::GLBufferHandle::get ( ) const

inline

Returns GL handle to the buffer object, or 0 if no GL buffer is owned.

reset()

void kanzi::GLBufferHandle::reset

(

)

Destroys the GL buffer object currently managed by the GLBufferHandle (if any)

operator bool_type()

kanzi::GLBufferHandle::operator bool_type ( ) const
