Class DtdModelBuilder

java.lang.Object

com.sun.xml.dtdparser.DTDHandlerBase

pro.projo.generation.dtd.DtdModelBuilder

All Implemented Interfaces:

com.sun.xml.dtdparser.DTDEventListener, EventListener

public class DtdModelBuilder
extends com.sun.xml.dtdparser.DTDHandlerBase

The DtdModelBuilder builds an in-memory model of a DTD. One big drawback with Sun's classic DTD parser is that many crucial pieces of information are not yet available when an element is processed. For example, it may be important to know if an element is part of a sequence or a choice, however that information will not be available until the first connector is encountered. For the first element in a model group this information will therefore only be available after the fact. Similarly, a model group's occurrence constraints are not known until the end of the group, and any sort of processing decisions for elements in the group that might depend on this information will have to be postponed. Rather than dealing with all kinds of delayed decisions when processing a DTD, it is often more convenient to build up a complete model ahead of time and so that any validation or code generation can occur with all necessary information already available.
