Public Member Functions
void	changeBindingPoint (int theBindingPoint)
Public Member Functions inherited from Wizt::GLMapMemory
void	setData (size_t length, const StorageFlags &SF) const
	Reserve data only.
void	setSubData (size_t offset, const void *data, size_t length) const override
	Set a subset of the data, which is more efficient than setData();.
Public Member Functions inherited from Wizt::MapMemory
void	setData (size_t length, const StorageFlags &SF) const
	Reserve data only.
Public Member Functions inherited from Wizt::UniformBuffer
bool	activate (const Anemone &) override
	Activate this tentacle.
bool	deactivate (const Anemone &) override
	Deactivate this tentacle.
Public Member Functions inherited from Wizt::Anemone::Tentacle
virtual const char *	getSamplerType () const
	If this tentacle refers to some texture sampler in a shader, then hereby return the type of this sampler is it occurs in the code.
virtual int	getTextureUnit () const
	Get the texture unit number which was specified during construction, if positive then it refers to some texture unit that is used in an associated shader.
virtual size_t	memsize () const
	Return the memory occupied by this buffer if it occupies memory at all. Otherwise, returns 0 (default).
virtual size_t	NumberOfElements () const
	Returns the number of elements provided and used by this object, if it refers to countable elements.
virtual bool	updateValue (VRenderContext &Context)
	Possibly update a tentacle from settings in a context.
Public Member Functions inherited from MemCore::ReferenceBase< Tentacle >
auto	getObjectCountID () const noexcept
	Get a unique ID for this object in the given domain.
bool	isIdentical (const WeakPtr< Tentacle, Tentacle > &PossibleSelf) const noexcept
	Check if this object is identical to the one used by the given pointer.
void	mkAutoDestructive ()
	Marks this object as being automatically destructed, e.g.
refcount_t	refcount () const noexcept
	The strong reference count.
	ReferenceBase (Tentacle *that) noexcept
	Constructor, initializes reference counter to zero.
const auto &	self () const
	Return weak pointer to the object self.
refcount_t	wrefcount () const noexcept
	The weak reference count.

Additional Inherited Members
Public Types inherited from MemCore::ReferenceBase< Tentacle >
using	reference_domain_t
	The type of the base class.
using	SelfPtr_t
	Type for a pointer to this object itself.
Public Attributes inherited from Wizt::Anemone::Tentacle

	A bit mask telling whether this tentacle should participate in the waving of an Anemone.
Protected Types inherited from Wizt::BufferID
enum	type
	Possible types of buffer ID's. More...
Protected Member Functions inherited from Wizt::BufferID
bool	bindBuffer () const
	const version of bind(), does not create a buffer ID.
bool	bindBufferWithPossibleCreation ()
	Non-const version of bind().
	BufferID (const type bufferType) noexcept
	The constructor does not yet create openGL buffers yet.
GLuint	createId () noexcept
	If no valid ID yet, call glCreateBuffers().
GLuint	getId () const noexcept
	Get an Id without attempting to generate it.
bool	isbound () const throw ()
	Verification function: buffer is bound?
bool	isIndexBuffer () const
	Check whether this is an index buffer.
bool	isVertexArray () const
	Check whether this is a vertex array.
GLuint	makeId ()
	On first access, OpenGL buffers will be generated. This function must be called from within a valid OpenGL context.
GLuint	operator() ()
	On first access, OpenGL buffers will be generated. This function must be called from within a valid OpenGL context.
	~BufferID () noexcept
	Deletion of created OpenGL buffers. Note that this might be problematic here if called outside a valid OpenGL context.
Protected Member Functions inherited from MemCore::ReferenceBase< Tentacle >
virtual void	extremeUnction ()
	A virtual function that will be called just before the object is destroyed.
ReferenceBase &	operator= (const ReferenceBase &R)
	Protected assignment operator (should not be called).
void	suicide ()
	Delete this.
virtual	~ReferenceBase ()
	Virtual destructor.
Protected Attributes inherited from Wizt::BufferID
const type	target
	The target type of this buffer ID.

changeBindingPoint()

void Wizt::GLUniformBuffer::changeBindingPoint

(

int

theBindingPoint

)

• The binding point must match what the shader expects (via layout(binding = N) or glUniformBlockBinding)
• Changing the buffer at a binding point affects all shaders referencing that point
