Method Detail

getRowCount

public int getRowCount()

Gets the number of rows in the matrix. Cost matrices are square so it is the same as the column count, i.e. the size of the matrix.

Returns:

the row count

getColumnCount

public int getColumnCount()

Gets the number of columns in the matrix. Cost matrices are square so it is the same as the row count, i.e. the size of the matrix.

Returns:

the row count

getValueAt

public java.lang.Object getValueAt(int row,
                                   int column)

Returns a value at the specified position in the cost matrix.

Parameters:

row - the row position

column - the column position

Returns:

the value

setValueAt

public void setValueAt(java.lang.Object aValue,
                       int rowIndex,
                       int columnIndex)

Sets a value at a specified position in the cost matrix.

Parameters:

aValue - the new value (should be of type Double).

rowIndex - the row position

columnIndex - the column position

isCellEditable

public boolean isCellEditable(int rowIndex,
                              int columnIndex)

Indicates whether a cell in the table is editable. In this case all cells are editable so true is always returned.

Parameters:

rowIndex - the row position

columnIndex - the column position

Returns:

true

getColumnClass

public java.lang.Class getColumnClass(int columnIndex)

Indicates the class of the objects within a column of the table. In this case all columns in the cost matrix consist of double values so Double.class is always returned.

Parameters:

columnIndex - the column position

Returns:

Double.class
