Detailed Description

Render value updater for render state.

This is an abstract class that is inherited and specialized by property value type.

Constructor & Destructor Documentation

kanzi::RenderStatePropertyNotificationHandler::RenderStatePropertyNotificationHandler ( )

explicitprotecteddefault

Empty constructor.

kanzi::RenderStatePropertyNotificationHandler::RenderStatePropertyNotificationHandler	(	AbstractPropertyType	propertyType,
		Node *	node
	)

inlineexplicitprotected

Constructor Has no handle.

Should only used for blend mode.

Parameters

propertyType	Property type to listen on.
node	Node to listen for changes on.

kanzi::RenderStatePropertyNotificationHandler::RenderStatePropertyNotificationHandler	(	AbstractPropertyType	propertyType,
		Node *	node,
		GlRenderState::HandleType	handle,
		ShaderProgram::UniformTransformation	transformation
	)

Parameters

propertyType	Property type to listen on.
node	Node to listen for changes on.
handle	Handle into the render state.
transformation	Uniform transformation.

Member Function Documentation

void kanzi::RenderStatePropertyNotificationHandler::update	(	GlRenderState &	renderState,
		PropertyObject *	object,
		Material &	material
	)

Update render state with new values acquirable from this.

Do not update if dirty flag has not been set (property is not marked as dirty).

Parameters

renderState	Render state to update.
object	Fallback object for property value. Can be 0.
material	Fallback material for property value.

Since: Kanzi 3.9.1 data type of object parameter changed from Object* to PropertyObject*.

int kanzi::RenderStatePropertyNotificationHandler::getHandle ( ) const

inline

Access handle.

Returns: Handle.

bool kanzi::RenderStatePropertyNotificationHandler::isDirty ( ) const

inline

Returns whether the container is dirty.

Returns: If the container is dirty, true, otherwise false.

Since: Kanzi 3.9.7

void kanzi::RenderStatePropertyNotificationHandler::setDirty ( bool enabled )

inline

Sets the dirty flag state.

Parameters

enabled The state of the dirty flag.

ShaderProgram::UniformTransformation kanzi::RenderStatePropertyNotificationHandler::getTransformation ( ) const

inlineprotected

Gets the uniform transformation.

Returns: Uniform transformation for the render value.

Since: Kanzi 3.9.7 moved from RenderValuePropertyNotificationHandlerBase.

virtual void kanzi::RenderStatePropertyNotificationHandler::updateOverride	(	GlRenderState &	renderState,
		PropertyObject *	object,
		Material &	material
	)

protectedpure virtual

Perform type-specific update.

Parameters

renderState	Render state to update.
object	Fallback object for property value, may be 0 for no object.
material	Fallback material for property value.

Since: Kanzi 3.9.1 data type of object parameter changed from Object* to PropertyObject*.

Implemented in kanzi::TypedRenderStateRangePropertyNotificationHandler< T >, kanzi::BlendModeRenderStatePropertyNotificationHandler, and kanzi::TypedRenderStatePropertyNotificationHandler< T >.

void kanzi::RenderStatePropertyNotificationHandler::onPropertyChanged ( PropertyNotificationReason )

overrideprotectedvirtual

AbstractPropertyNotificationHandler::onPropertyChanged() implementation.

Implements kanzi::AbstractPropertyNotificationHandler.
