详细描述
The QScxmlCompiler class is a compiler for SCXML files.
Parses an SCXML file and dynamically instantiates a state machine for a successfully parsed SCXML file. If parsing fails, the new state machine cannot start. All errors are returned by QScxmlStateMachine::parseErrors().
To load an SCXML file, QScxmlStateMachine::fromFile or QScxmlStateMachine::fromData should be used. Using QScxmlCompiler directly is only needed when the compiler needs to use a custom QScxmlCompiler::Loader.
成员函数
QScxmlCompiler::QScxmlCompiler(QXmlStreamReader *reader)
Creates a new SCXML compiler for the specified reader.
QScxmlCompiler::~QScxmlCompiler()
Destroys the SCXML compiler.
QScxmlStateMachine *QScxmlCompiler::compile()
Parses an SCXML file and creates a new state machine from it.
If parsing is successful, the returned state machine can be initialized and started. If parsing fails, QScxmlStateMachine::parseErrors() can be used to retrieve a list of errors.
QVector<QScxmlError> QScxmlCompiler::errors() const
Returns the list of parse errors.
QString QScxmlCompiler::fileName() const
Returns the file name associated with the current input.
参见 setFileName().
Loader *QScxmlCompiler::loader() const
Returns the loader that is currently used to resolve and load URIs for the SCXML compiler.
参见 setLoader().
void QScxmlCompiler::setFileName(const QString &fileName)
Sets the file name for the current input to fileName.
The file name is used for error reporting and for resolving relative path URIs.
参见 fileName().
void QScxmlCompiler::setLoader(Loader *newLoader)
Sets newLoader to be used for resolving and loading URIs for the SCXML compiler.
参见 loader().
