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
propertyTypeProperty type to listen on.
nodeNode to listen for changes on.
kanzi::RenderStatePropertyNotificationHandler::RenderStatePropertyNotificationHandler ( AbstractPropertyType  propertyType,
Node node,
GlRenderState::HandleType  handle,

handleHandle into the render state.
transformationUniform 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
renderStateRender state to update.
objectFallback object for property value. Can be 0.
materialFallback 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
enabledThe 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
renderStateRender state to update.
objectFallback object for property value, may be 0 for no object.
materialFallback 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 >.
