Method Detail

dimension

public int dimension()

Description copied from interface: IDataPoint

Get the dimension of the IDataPoint, i.e. the number of coordinates the point has.

Specified by:

dimension in interface IDataPoint

Returns:

The dimension.

coordinate

public IMeasurement coordinate(int coord)

Description copied from interface: IDataPoint

Get the IMeasurement for a given coordinate.

Specified by:

coordinate in interface IDataPoint

Parameters:

coord - The coordinate.

Returns:

The corresponding IMeasurement.

lowerExtent

public double lowerExtent(int coord)
                   throws IllegalArgumentException

Get the lower value for a give axis. This method is not in the IDataPoint interface and is here for efficiency reasons

Parameters:

coord - The coordinate of the axis.

Returns:

The lower edge of the corresponding axis.

Throws:

IllegalArgumentException - if coord < 0 or coord >= dimension() or if the set is empty.

upperExtent

public double upperExtent(int coord)
                   throws IllegalArgumentException

Get the upper value for a give axis. This method is not in the IDataPoint interface and is here for efficiency reasons

Parameters:

coord - The coordinate of the axis.

Returns:

The upper edge of the corresponding axis.

Throws:

IllegalArgumentException - if coord < 0 or coord >= dimension() or if the set is empty.

stateChanged

public void stateChanged(EventObject e)

Specified by:

stateChanged in interface AIDAListener

clear

public void clear()
