public abstract class QualifiedName extends java.lang.Object
Abstraction over a qualified name. Unifies Node-based qualified names and string-based names, allowing to lazily parse strings and represent a pre-parsed qualified name without the overhead of a whole Node. Essentially, a qualified name is a linked list of components, starting from the outermost property access and ending with the root of the name, which is a simple name with no owner.
