com.ctc.wstx.dtd.ModelNode

Direct Known Subclasses:

ChoiceModel, ConcatModel, OptionalModel, StarModel, TokenModel

public abstract class ModelNode
extends Object

Abstract base class for classes constructed from ContentSpec objects, when they get rewritten (when their ContentSpec.rewrite() gets called). These nodes are then used for constructing complete DFA states for validation.
