public interface ILcdMatrixView

An ILcdMatrixView represents a regular 2D data structure where values can be accessed through rows and columns. Every entry in this structure can have a point associated with it. Note that the distribution of the points does not need to be regular. It is possible to retrieve the coordinates of the point associated with an entry using the methods retrieveAssociatedPointX(int, int) and retrieveAssociatedPointY(int, int).

Method Summary

Modifier and Type	Method and Description
int	getColumnCount() Returns the number of columns in this matrix view.
int	getRowCount() Returns the number of rows in this matrix view.
double	getValue(int aColumnIndex, int aRowIndex) Returns the value of the matrix pixel corresponding to the column index aColumnIndex and the row index aRowIndex.
double	retrieveAssociatedPointX(int aColumnIndex, int aRowIndex) Returns the x-coordinate of the associated point corresponding to the column index aColumnIndex and the row index aRowIndex.
double	retrieveAssociatedPointY(int aColumnIndex, int aRowIndex) Returns the y-coordinate of the associated point corresponding to the column index aColumnIndex and the row index aRowIndex.

Method Detail

getValue

double getValue(int aColumnIndex,
                int aRowIndex)

Returns the value of the matrix pixel corresponding to the column index aColumnIndex and the row index aRowIndex.

Parameters:

aColumnIndex - the column index, positive and smaller than the columncount.

aRowIndex - the row index, positive and smaller than the rowcount.

Returns:

the value of the matrix pixel.

retrieveAssociatedPointX

double retrieveAssociatedPointX(int aColumnIndex,
                                int aRowIndex)

Returns the x-coordinate of the associated point corresponding to the column index aColumnIndex and the row index aRowIndex.

Parameters:

aColumnIndex - the column index, positive and smaller than the columncount.

aRowIndex - the row index, positive and smaller than the rowcount.

Returns:

the x-coordinate of the associated point.

retrieveAssociatedPointY

double retrieveAssociatedPointY(int aColumnIndex,
                                int aRowIndex)

Returns the y-coordinate of the associated point corresponding to the column index aColumnIndex and the row index aRowIndex.

Parameters:

aColumnIndex - the column index, positive and smaller than the columncount.

aRowIndex - the row index, positive and smaller than the rowcount.

Returns:

the y-coordinate of the associated point.

getColumnCount

int getColumnCount()

Returns:

the number of columns in this matrix view, strictly positive.

getRowCount

int getRowCount()

Returns the number of rows in this matrix view. The number of rows shall be strictly positive.

Returns:

the number of rows in this matrix view, strictly positive.
