Method Detail

getValueAt

Object getValueAt(Object object,
                  int columnIndex)

Returns the value for the attribute number columnIndex in the given object.

Parameters:

object - The object (row) in which the value is to be looked up.

columnIndex - The column denoting the attribute whose value is to be looked up.

setValueAt

void setValueAt(Object value,
                Object object,
                int columnIndex)

Sets the value for the attribute number columnIndex in the given object to the given value.

Parameters:

value - The new value.

object - The object (row) in which the value has to be changed.

columnIndex - The column denoting the attribute whose value has to be changed.

getDoubleAt

double getDoubleAt(Object object,
                   int columnIndex)

Returns the value for the attribute number columnIndex in the given object.

This method should only be used for columns whose type is Double. For other types of columns, this method will do a conversion from the object returned by getValueAt, which may be inefficient or inaccurate or raise exceptions.

Parameters:

object - The object (row) in which the value has to be looked up.

columnIndex - The column denoting the attribute whose value has to be looked up.

setDoubleAt

void setDoubleAt(double value,
                 Object object,
                 int columnIndex)

Sets the value for the attribute number columnIndex in the given object to the given value.

This method should only be used for columns whose type is Double. For other types of columns, this method will do a conversion to the column type, which may be inefficient or inaccurate or raise exceptions.

Parameters:

value - The new value.

object - The object (row) in which the value has to be changed.

columnIndex - The column denoting the attribute whose value has to be changed.
