• **kwargs – Keywords arguments. ( ** )

roles

This method is the property for self.__roles attribute.

Returns:self.__roles. ( Dictionary )

flags

This method is the property for self.__flags attribute.

Returns:self.__flags. ( Integer )

class umbra.ui.nodes.GraphModelNode(*args, **kwargs)

Bases: foundations.nodes.AbstractCompositeNode

• parent – Node parent. ( AbstractNode / AbstractCompositeNode )
• children – Children. ( List )
• format – Format. ( Object )
• **kwargs – Keywords arguments. ( ** )

format

This method is the property for self.__format attribute.

Returns:self.__format. ( Object )
