/*
    \fn QByteArray QDeclarativeCustomParser::compile(const QList<QDeclarativeCustomParserProperty> & 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 QDeclarativeCustomParser::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().

    Errors should be reported using qmlInfo(object).

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