Member Function Documentation

update()

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*.

getHandle()

int kanzi::RenderStatePropertyNotificationHandler::getHandle ( ) const

inline

Access handle.

Returns

Handle.

isDirty()

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

setDirty()

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

inline

Sets the dirty flag state.

Parameters

enabled

The state of the dirty flag.

getTransformation()

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.

updateOverride()

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

onPropertyChanged()

void kanzi::RenderStatePropertyNotificationHandler::onPropertyChanged ( PropertyNotificationReason )

overrideprotectedvirtual

AbstractPropertyNotificationHandler::onPropertyChanged() implementation.

Implements kanzi::AbstractPropertyNotificationHandler.
