java.lang.Object
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.
