/*!
    \class QmlCustomParser
    \brief The QmlCustomParser class allows you to add new arbitrary types to QML.
    \internal

    By subclassing QmlCustomParser, you can add a parser for
    building a particular type.

    The subclass must implement compile() and setCustomData(), and define
    itself in the meta type system with the macro:

    \code
    QML_DEFINE_CUSTOM_TYPE(Module, MajorVersion, MinorVersion, Name, TypeClass, ParserClass)
    \endcode
*/

/*
    \fn QByteArray QmlCustomParser::compile(const QList<QmlCustomParserProperty> & properties)

    The custom parser processes \a properties, and returns
    a QByteArray containing data meaningful only to the
    custom parser; the type engine will pass this same data to
    setCustomData() when making an instance of the data.

    Errors must be reported via the error() functions.

    The QByteArray may be cached between executions of the system, so
    it must contain correctly-serialized data (not, for example,
    pointers to stack objects).
*/

/*
    \fn void QmlCustomParser::setCustomData(QObject *object, const QByteArray &data)

    This function sets \a object to have the properties defined
    by \a data, which is a block of data previously returned by a call
    to compile().

    The \a object will be an instance of the TypeClass specified by QML_DEFINE_CUSTOM_TYPE.
