Interface GridDataAccess<T>

Type Parameters:

T - primitive array type of cell data, e.g. short[].

All Known Implementing Classes:

GridDataAccessImp.Cells, GridDataAccessImp.VolatileCells

public interface GridDataAccess<T>

Access to data at positions in a cell grid.

Method Summary

int	cellSize(int d, int cellGridPosition) From the position of a cell in the grid, compute the size of the cell in dimension d.
void	fwd(int d)
T	get() Get the primitive array with data of grid cell at current position.
int[]	getPosition()
int	imgSize(int d) Get the image size in dimension d in pixels.
void	setPosition(int[] position)
void	setPosition(int position, int d)

Method Detail

fwd

void fwd(int d)

setPosition

void setPosition(int position,
                 int d)

setPosition

void setPosition(int[] position)

getPosition

int[] getPosition()

get

T get()

Get the primitive array with data of grid cell at current position.

Returns:

data at current position, or null if data is not valid.

cellSize

int cellSize(int d)

Get the size of a standard cell in dimension d. Cells on the max border of the image may be truncated and may therefore have different size.

Parameters:

d - dimension index

cellSize

int cellSize(int d,
             int cellGridPosition)

From the position of a cell in the grid, compute the size of the cell in dimension d. The size will be the standard cell size, unless the cell is at the border of the image, in which case it might be truncated.

Parameters:

d - dimension index

cellGridPosition - grid coordinates of the cell in dimension d.

Returns:

size of the cell in dimension d.

imgSize

int imgSize(int d)

Get the image size in dimension d in pixels. Note, that this is the number of pixels in all cells combined, not the number of cells!

Parameters:

d - dimension index
