Detailed Description

GLTextureHandle manages RAII ownership for GL texture object.

Constructor & Destructor Documentation

GLTextureHandle() [1/4]

kanzi::GLTextureHandle::GLTextureHandle ( )

explicit

Constructs an empty GLTextureHandle which does not own any GL texture object.

GLTextureHandle() [2/4]

kanzi::GLTextureHandle::GLTextureHandle ( Renderer * renderer )

explicit

Creates a new GL texture object with renderer and constructs a GLTextureHandle which owns it.

Parameters

renderer

Renderer

~GLTextureHandle()

kanzi::GLTextureHandle::~GLTextureHandle

(

)

GLTextureHandle() [3/4]

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

explicit

Creates a wrapper for pre-existing GL texture object.

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

Parameters

renderer	Renderer
handle	Pre-existing GL texture object name
takeOwnership	Should newgly created GLTextureHandle take ownership of the GL texture object

GLTextureHandle() [4/4]

kanzi::GLTextureHandle::GLTextureHandle ( GLTextureHandle && other )

inline

Member Function Documentation

release()

unsigned int kanzi::GLTextureHandle::release

(

)

Releases the ownership of the GL texture if any.

get() returns 0 after the call.

Returns

Handle to the GL texture object

operator=()

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

inline

get()

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

inline

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

reset()

void kanzi::GLTextureHandle::reset

(

)

Destroys the GL texture object currently managed by the GLTextureHandle (if any)

operator bool_type()

kanzi::GLTextureHandle::operator bool_type ( ) const
