segment - the selected element representing a segment ring (specific clustering)

addToSelection - flag for adding segment to current selection

Parameters:

segment - Segment to deselect

selectSegment

protected void selectSegment(Segment segment)

Select a segment

Parameters:

segment - Segment to select

indexOfSegment

public int indexOfSegment(Segment segment)

Get the index of a selected segment.

Parameters:

segment - Segment to find

Returns:

Index, or -1

getLongName

public String getLongName()

Description copied from interface: Result

A "pretty" name for the result, for use in titles, captions and menus.
