All Implemented Interfaces:

NameClassAndExpression, Serializable

public class ExternalElementExp

extends ElementExp

place holder for imported element declaration. This class derives ElementExp because "elementDecl" is a constraint over one element. This class also provides stub methods so that programs who are not aware to divide&validate can gracefully degrade.

Method Detail

getNameClass

public NameClass getNameClass()

Description copied from class: ElementExp

obtains a constraint over tag name. ElementExp is cannot be shared because NameClass has to be mutable to absorb the difference of RELAX and TREX. In case of TREX, name class will be determined when parsing ElementExp itself. Thus effectively it's immutable. In case of RELAX, name class will be determined when its corresponding Clause object is parsed.
