Method Detail

add

boolean add(int row,
            int column,
            int score)

It is equal to create an integer cell and then add the cell to the sparse matrix.

Parameters:

row - the row of the cell

column - the column of the cell

score - the score of the cell

Returns:

true if added successfully

getRowSum

long getRowSum(int row)

Parameters:

row - the index of the row

Returns:

the summation score of the given row.
