      • SchemaParser

        public SchemaParser​(Definition definition)
                     throws java.lang.Exception
        Constructor for a WSDL definition. This will parse the schemas defined, verify them and create a validator. The property wrappers are then created.
        Parameters:
        definition - The definition.
        Throws:
        java.lang.Exception - For errors in parsing.

      • getSchemas

        public XSSchemaSet getSchemas()
        Gets the Schemas parsed.
        Returns:
        The schems.
      • getSchemaValidator

        public javax.xml.validation.Validator getSchemaValidator()
        Gets the schema validator.
        Returns:
        The XML schema validator.
      • getSchemaSources

        public java.util.Map<java.lang.String,​java.lang.String> getSchemaSources()
        Gets the Schema sources map.
        Returns:
        A map with the namespaces as keys and XSD source as values.
      • warning

        public void warning​(org.xml.sax.SAXParseException exception)
                     throws org.xml.sax.SAXException
        Receive notification of a warning.

        SAX parsers will use this method to report conditions that are not errors or fatal errors as defined by the XML recommendation. The default behavior is to take no action.

        The SAX parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end.

        Filters may use this method to report other, non-XML warnings as well.

        Specified by:
        warning in interface org.xml.sax.ErrorHandler
        Parameters:
        exception - The warning information encapsulated in a SAX parse exception.
        Throws:
        org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
        See Also:
        SAXParseException
      • error

        public void error​(org.xml.sax.SAXParseException exception)
                   throws org.xml.sax.SAXException
        Receive notification of a recoverable error.

        This corresponds to the definition of "error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a validating parser would use this callback to report the violation of a validity constraint. The default behavior is to take no action.

        The SAX parser must continue to provide normal parsing events after invoking this method: it should still be possible for the application to process the document through to the end. If the application cannot do so, then the parser should report a fatal error even if the XML recommendation does not require it to do so.

        Filters may use this method to report other, non-XML errors as well.

        Specified by:
        error in interface org.xml.sax.ErrorHandler
        Parameters:
        exception - The error information encapsulated in a SAX parse exception.
        Throws:
        org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
        See Also:
        SAXParseException
      • fatalError

        public void fatalError​(org.xml.sax.SAXParseException exception)
                        throws org.xml.sax.SAXException
        Receive notification of a non-recoverable error.

        There is an apparent contradiction between the documentation for this method and the documentation for ContentHandler.endDocument(). Until this ambiguity is resolved in a future major release, clients should make no assumptions about whether endDocument() will or will not be invoked when the parser has reported a fatalError() or thrown an exception.

        This corresponds to the definition of "fatal error" in section 1.2 of the W3C XML 1.0 Recommendation. For example, a parser would use this callback to report the violation of a well-formedness constraint.

        The application must assume that the document is unusable after the parser has invoked this method, and should continue (if at all) only for the sake of collecting additional error messages: in fact, SAX parsers are free to stop reporting any other events once this method has been invoked.

        Specified by:
        fatalError in interface org.xml.sax.ErrorHandler
        Parameters:
        exception - The error information encapsulated in a SAX parse exception.
        Throws:
        org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
