Method Detail

setElementDeclaration

public void setElementDeclaration(ElementDecl decl)
                           throws XPathException

setElementDeclaration is called immediately before the call on startElement. It identifies the element declaration that defines the just-started element, which in turn is used to create a Watch for constraints originating at this element.

Throws:

XPathException
