Method Detail

dimension

public int dimension()

Specified by:

dimension in interface hep.aida.IDataPoint

coordinate

public hep.aida.IMeasurement coordinate(int coord)

Specified by:

coordinate in interface hep.aida.IDataPoint

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.
