Method Detail

getResult

public final TREXGrammar getResult()

obtains parsed grammar object only if parsing was successful.

getResultAsGrammar

public Grammar getResultAsGrammar()

Description copied from class: GrammarReader

gets the parsed AGM. Should any error happens, this method returns null. derived classes should implement type-safe getGrammar method, along with this method.

Overrides:

getResultAsGrammar in class GrammarReader

getTargetNamespace

public final String getTargetNamespace()

createExpressionChildState

public State createExpressionChildState(State parent,
                                        StartTagInfo tag)

Description copied from class: GrammarReader

this method must be implemented by the derived class to create language-default expresion state.

Overrides:

createExpressionChildState in class GrammarReader

Following copied from class: com.sun.msv.reader.GrammarReader

Returns:

null if the start tag is an error.

wrapUp

public void wrapUp()

performs final wrap-up. This method is called from the RootState object, after the parsing is completed.

startElement

public void startElement(String a,
                         String b,
                         String c,
                         Attributes d)
                  throws SAXException

Overrides:

startElement in class XMLFilterImpl

endElement

public void endElement(String a,
                       String b,
                       String c)
                throws SAXException

Overrides:

endElement in class XMLFilterImpl
