      • getProperJavaClass

        public static java.lang.String getProperJavaClass​(java.lang.String _argType,
                                                  java.util.Set<java.lang.String> _includes)
        Converts a java class type to another type. This is used for converting e.g. CharSequence to String etc. It will also remove unnecessary package names like java.lang.
        Parameters:
        _argType - Argument to convert
        _includes - Set where additional includes will be added (should never be null!)
        Returns:
        String with proper type, if no converation could be done, original input is returned

      • convertJavaType

        public static java.lang.String convertJavaType​(java.lang.String _fqcn,
                                               boolean _usePrimitives)
        Transform certain java types to other java types (see CLASS_MAP).
        Parameters:
        _fqcn - fully qualified classname of the type to convert
        _usePrimitives - if true, boxed types will be converted to primitives
        Returns:
        converted type or original input

      • convertJavaBoxedTypeToPrimitive

        private static java.lang.String convertJavaBoxedTypeToPrimitive​(java.lang.String _clazzName)
        Converts certain boxed types to primitives.
        Parameters:
        _clazzName - class name of boxed type
        Returns:
        primitive or original input

      • getJavaTypeFromDBusType

        public static java.lang.String getJavaTypeFromDBusType​(java.lang.String _dbusType,
                                                       java.util.Set<java.lang.String> _javaIncludes)
                                                throws DBusException
        Converts a DBus data type string to java classname(s).
        Parameters:
        _dbusType - DBus data type string
        _javaIncludes - List where additional imports will be added to (should not be null!)
        Returns:
        Java classname, maybe null if no suitable input was given
        Throws:
        DBusException - on DBus error

      • getTypeAdv

        private static java.util.Map<java.lang.String,​java.util.List<java.lang.String>> getTypeAdv​(java.lang.reflect.Type _type)
                                                                                          throws DBusException
        Resolve java type recursively.
        Parameters:
        _type - Type object
        Returns:
