Method Detail

getMatchingElemDecl

public XSElementDecl getMatchingElemDecl(org.apache.xerces.xni.QName element,
                                         XSElementDecl exemplar)

substitutionGroupOK

protected boolean substitutionGroupOK(XSElementDecl element,
                                      XSElementDecl exemplar,
                                      short blockingConstraint)

inSubstitutionGroup

public boolean inSubstitutionGroup(XSElementDecl element,
                                   XSElementDecl exemplar)

reset

public void reset()
clear the internal registry of substitutionGroup information


addSubstitutionGroup

public void addSubstitutionGroup(XSElementDecl[] elements)
add a list of substitution group information.


getSubstitutionGroup

public XSElementDecl[] getSubstitutionGroup(XSElementDecl element)
get all elements that can substitute the given element, according to the spec, we shouldn't consider the {block} constraints. from the spec, substitution group of a given element decl also contains the element itself. but the array returned from this method doesn't containt this element.
