QScxmlCompiler ¶

概要 ¶

详细描述 ¶

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 parseErrors() .

To load an SCXML file, fromFile or fromData should be used. Using QScxmlCompiler directly is only needed when the compiler needs to use a custom Loader .

class QScxmlCompiler ( xmlReader ) ¶

QXmlStreamReader

Creates a new SCXML compiler for the specified reader .
