object Null extends MetaData with Product with Serializable

Essentially, every method in here is a dummy, returning Zero[T]. It provides a backstop for the unusual collection defined by MetaData, sort of a linked list of tails.

  5. def append(m: MetaData, scope: NamespaceBinding = TopScope): MetaData

    Updates this MetaData with the MetaData given as argument.

    Updates this MetaData with the MetaData given as argument. All attributes that occur in updates are part of the resulting MetaData. If an attribute occurs in both this instance and updates, only the one in updates is part of the result (avoiding duplicates). For prefixed attributes, namespaces are resolved using the given scope, which defaults to TopScope.

    returns

    a new MetaData instance that contains old, new and updated attributes
