ConfusionTableModel

public ConfusionTableModel(int[][] scoreCount,
                           String[] headers,

                           String columnHeaderDescription)

Constructs confusion table model from the score count and the headers.

Parameters:

scoreCount - a 2-D int array representing the confusion matrix.

headers - the names of the attributes to display in the table

rowHeaderDescription - row header description

columnHeaderDescription - column header description

Method Detail

getColumnCount

public int getColumnCount()

Column and row count are equal as this is a square matrix. Note: + 1 for the column header

getRowCount

public int getRowCount()

Column and row count are equal as this is a square matrix. Note: + 1 for the row header

getValueAt

public Object getValueAt(int rowIndex,
                         int columnIndex)

Returns the confusion matrix value at the corresponding position. Note: the first column contains like the column names also the attribute names.

getColumnName

public String getColumnName(int column)

Returns the column names, i.e. the attribute names of the confusion matrix.

Specified by:

getColumnName in interface TableModel

Overrides:

getColumnName in class AbstractTableModel

Parameters:

column - the index of the column in the table to display
