Hashcode typically derives from the Segment.toString()
representation so two Segment
s yield the same
Segment.hashCode()
if their Segment.toString()
representation matches.public boolean equals(Object obj)

Segment
is equal to another Segment
.
Equality is typically given if the Segment.toString()
representation matches.Copyright © 2017–2022 Pivotal Software, Inc.. All rights reserved.
