Method Detail

getParent

public ElementRules getParent()

gets the parent ElementRules object. when this object is used as a named, no-inline elementRule, this variable holds a reference to the parent ElementRules object. otherwise, null

getNameClass

public final 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.
