Detailed Description

GLTextureHandle manages RAII ownership for GL texture object.

Constructor & Destructor Documentation

kanzi::GLTextureHandle::GLTextureHandle ( )

explicit

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

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

explicit

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

Parameters

renderer Renderer

kanzi::GLTextureHandle::~GLTextureHandle ( )

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

kanzi::GLTextureHandle::GLTextureHandle ( KZ_RV_REF(GLTextureHandle) other )

inline

unsigned int kanzi::GLTextureHandle::release ( )

Releases the ownership of the GL texture if any.

get() returns 0 after the call.

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

inline

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

inline

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

void kanzi::GLTextureHandle::reset ( )

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

kanzi::GLTextureHandle::operator bool_type ( ) const
