public interface IZeroToOneMatrix<RowType,ColumnType>
extends IRdZeroToOneMatrix<RowType,ColumnType>

A matrix which is able to store values in [0, 1], i.e., doubles between 0 and 1 inclusive, at a set of positions, each position being represented by a row and a column.

Vocabulary note: an entry can be a value or can be null, a value is a double between zero and one.

Method Summary

boolean	isValid(double value)
void	put(RowType row, ColumnType column, double value) Puts a value in this matrix at the position specified by the given row and column.
Double	remove(RowType row, ColumnType column) Removes the value in this matrix at the position specified by the given row and column.

Method Detail

put

void put(RowType row,
         ColumnType column,
         double value)

Puts a value in this matrix at the position specified by the given row and column.

Parameters:

row - not null.

column - not null.

value - between zero and one (inclusive).

remove

Double remove(RowType row,
              ColumnType column)

Removes the value in this matrix at the position specified by the given row and column. If there was no value at that position, this method has no effect.

Parameters:

row - not null.

column - not null.

Returns:

the value which was previously at the given position. Returns null iff there was no value at that position (and, hence, nothing was removed).

isValid

boolean isValid(double value)
