详细描述

剖析 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 ().

要加载 SCXML 文件， QScxmlStateMachine::fromFile or QScxmlStateMachine::fromData should be used. Using QScxmlCompiler directly is only needed when the compiler needs to use a custom QScxmlCompiler::Loader .

成员函数文档编制

QScxmlCompiler:: QScxmlCompiler ( QXmlStreamReader * reader )

创建新的 SCXML 编译器为指定 reader .

QScxmlCompiler:: ~QScxmlCompiler ()

销毁 SCXML 编译器。

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

返回剖析错误的列表。

QString QScxmlCompiler:: fileName () const

Returns the file name associated with the current input.

另请参阅 setFileName ().

QScxmlCompiler::Loader *QScxmlCompiler:: loader () const

Returns the loader that is currently used to resolve and load URIs for the SCXML compiler.

另请参阅 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.

另请参阅 fileName ().

void QScxmlCompiler:: setLoader ( QScxmlCompiler::Loader * newLoader )

设置 newLoader to be used for resolving and loading URIs for the SCXML compiler.
