All Implemented Interfaces:

NameClassAndExpression, Serializable

Direct Known Subclasses:

AnyOtherElementExp, ElementDeclExp.XSElementExp, ElementPattern, ElementRule, ExternalElementExp

public abstract class ElementExp

extends Expression

implements NameClassAndExpression

Element declaration. For RELAX, this is a base implementation of 'elementRule' declaration. For TREX, this is a base implementation of 'element' pattern. Each grammar must/can provide only one concrete implementation. Therefore, they cannot override visit method.

This class can be extended.

Field Detail

contentModel

public Expression contentModel

content model of this element declaration.

ignoreUndeclaredAttributes

public boolean ignoreUndeclaredAttributes

a flag that indicates undeclared attributes should be ignored.

Constructor Detail

ElementExp

public ElementExp(Expression contentModel,
                  boolean ignoreUndeclaredAttributes)

Method Detail

getContentModel

public final Expression getContentModel()

Specified by:

getContentModel in interface NameClassAndExpression

getNameClass

public abstract NameClass getNameClass()

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.
