Class TrackSegment

java.lang.Object
  jmri.jmrit.display.layoutEditor.TrackSegment

public class TrackSegment
extends Object

TrackSegment is a segment of track on a layout linking two nodes of the layout. A node may be a LayoutTurnout, a LevelXing or a PositionablePoint.

PositionablePoints have 1 or 2 connection points. LayoutTurnouts have 3 or 4 (crossovers) connection points, designated A, B, C, and D. LevelXing's have 4 connection points, designated A, B, C, and D.

TrackSegments carry the connectivity information between the three types of nodes. Track Segments serve as the lines in a graph which shows layout connectivity. For the connectivity graph to be valid, all connections between nodes must be via TrackSegments.

TrackSegments carry Block information, as do LayoutTurnouts and LevelXings.

TrackSegments may be drawn as dashed lines or solid lines. In addition TrackSegments may be hidden when the panel is not in EditMode.
