Method Detail

localizeMessage

protected java.lang.String localizeMessage(java.lang.String propertyName,
                                           java.lang.Object[] args)

Description copied from class: GrammarReader

formats localized message with arguments

Specified by:

localizeMessage in class GrammarReader

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 should returns null. derived classes should implement type-safe getGrammar method, along with this method.

Specified by:

getResultAsGrammar in class GrammarReader

getTargetNamespace

public final java.lang.String getTargetNamespace()

createNameClassChildState

protected State createNameClassChildState(State parent,
                                          StartTagInfo tag)

createExpressionChildState

                                        StartTagInfo tag)

Description copied from class: GrammarReader

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

Specified by:

createExpressionChildState in class 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.

This method has to be called after the run-away expression check is done.
