      • createSuitableNativeImg

        public NativeImg<ARGBType,​? extends IntAccess> createSuitableNativeImg​(NativeImgFactory<ARGBType> storageFactory,
                                                                                     long[] dim)
        Description copied from interface: NativeType
        The NativeType creates the NativeImg used for storing image data; based on the given storage strategy and its size. It basically only decides here which BasicType it uses (float, int, byte, bit, ...) and how many entities per pixel it needs (e.g. 2 floats per pixel for a complex number). This enables the separation of containers and the basic types.
        Specified by:
        createSuitableNativeImg in interface NativeType<ARGBType>
        Parameters:
        storageFactory - which storage strategy is used
        dim - the dimensions
        Returns:
        the instantiated NativeImg where only the Type knows the BasicType it contains.
      • updateContainer

        public void updateContainer​(java.lang.Object c)
        Description copied from interface: NativeType
        This method is used by an accessor (e.g., a Cursor) to request an update of the current data array.

        As an example consider a CellCursor moving on a CellImg. The cursor maintains a NativeType which provides access to the image data. When the cursor moves from one cell to the next, the underlying data array of the NativeType must be switched to the data array of the new cell.

        To achieve this, the CellCursor calls updateContainer() with itself as the argument. updateContainer() in turn will call NativeImg.update(Object) on it's container, passing along the reference to the cursor. In this example, the container would be a CellImg. While the NativeType does not know about the type of the cursor, the container does. CellImg knows that it is passed a CellCursor instance, which can be used to figure out the current cell and the underlying data array, which is then returned to the NativeType.

        The idea behind this concept is maybe not obvious. The NativeType knows which basic type is used (float, int, byte, ...). However, it does not know how the data is stored (ArrayImg, CellImg, ...). This prevents the need for multiple implementations of NativeType .

        Specified by:
        updateContainer in interface NativeType<ARGBType>
        Parameters:
        c - reference to an accessor which can be passed on to the container (which will know what to do with it).

        public ARGBType createVariable()
        Description copied from interface: Type
        Creates a new Type variable which can only store one value.
        Specified by:
        createVariable in interface Type<ARGBType>
        Returns:
        a new Type variable
      • copy

        public ARGBType copy()
        Description copied from interface: Type
        Creates a new Type variable that has the value of this Type
        Specified by:
        copy in interface Type<ARGBType>
        Returns:

      • getEntitiesPerPixel

        public Fraction getEntitiesPerPixel()
        Description copied from interface: NativeType
        Get the number of entities in the storage array required to store one pixel value. A pixel value may be spread over several or less than one entity. For example, a complex number may require 2 entries of a float[] array to store one pixel. Or a 12-bit type might need 12/64th entries of a long[] array.
        Specified by:
        getEntitiesPerPixel in interface NativeType<ARGBType>
        Returns:
        the number of storage type entities required to store one pixel value.
