All Known Implementing Classes:

public interface Lookup

Interface for lookup capabilities. This allows to retrieve additional implementation aspects that are not provided by an interface contract. This is used mainly by the parse and write context classes, that allow to pass arbitrary additional information into the current parse/write state without introducing additional dependencies into the core library classes.
