org.eclipse.wst.wsdl.util
Class WSDLParser

java.lang.Object
  extended by org.xml.sax.helpers.DefaultHandler
      extended by 
org.eclipse.wst.wsdl.util.WSDLParser
All Implemented Interfaces:
org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.ext.LexicalHandler
public class WSDLParser

extends org.xml.sax.helpers.DefaultHandler
implements org.xml.sax.ext.LexicalHandler

The SAX Parser for the WSDL model. This class' main responsibility is to compute line/column information for all elements in the source XML document. This information is stored in a map of each node to its user data.

Note: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

[ISSUE] Most of this class' implementation is a clone of XSDParser. There are plans to work on closely integrating this class and XSDParser to provide for the most efficient processing of inline schemas.
