Trait for a type tree, a structure that provides methods to inspect type relationships. This is used for getting reference sub-types, and for events.

Required Methods

fn is_subtype_of(&self, child: &NodeId, ancestor: &NodeId) -> bool

Return true if child is a descendant of ancestor, meaning they are connected with a chain of HasSubtype references.

fn get_node<'a>(&'a self, node: &NodeId) -> Option<TypeTreeNode<'a>>

Get a reference to the node with ID node.

fn get(&self, node: &NodeId) -> Option<NodeClass>

Get the node class of a type in the type tree given by node.

fn find_type_prop_by_browse_path( &self, type_id: &NodeId, path: &[QualifiedName], ) -> Option<&TypeProperty>

Find a property of a type from its browse path.

fn get_supertype<'a>(&'a self, node: &NodeId) -> Option<&'a NodeId>

Get the supertype of the given node.

fn namespaces(&self) -> &NamespaceMap

Get the namespace map used by this type tree.
