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
rendererRenderer

◆ ~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
rendererRenderer
handlePre-existing GL buffer object name
takeOwnershipShould 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
inline
