public class Segment
extends Indexed

This immutable class represents a segment. The segment connects two junctions (called the "A" junction and the "B" junction), has a length, and is part of a route.

Constructor Index

Segment(MutableSegment, BoardBuilder): constructs an object like the MutableSegment parameter.

Method Index

equals(Object): compares for content-equality.
getAjunc(): returns the segment's "A" junction.
getBjunc(): returns the segment's "B" junction.
getLength(): returns the segment's length.
getOther(Junction): given one of the two endpoint junctions, returns the other.
getRoute(): returns the segment's route.
toString(): returns a string representation.

Constructors

Segment

 public Segment(MutableSegment ms,
                BoardBuilder bb)

constructs an object like the MutableSegment parameter.

Methods

equals

 public boolean equals(Object ob)

compares for content-equality.

Overrides:: equals in class Indexed

getAjunc

 public Junction getAjunc()

returns the segment's "A" junction.

getBjunc

 public Junction getBjunc()

returns the segment's "B" junction.

getLength

 public int getLength()

returns the segment's length.

getRoute

 public Route getRoute()

returns the segment's route.

getOther

 public Junction getOther(Junction junc)

given one of the two endpoint junctions, returns the other. Otherwise, returns null. (One can also use this to test whether the Segment abuts a particular Junction.)

toString

 public String toString()

returns a string representation. It shows A-junction-name, B-junction-name, route-name, and length.

Overrides:: toString in class Object
