Should Line be changed to Segment?

Referring to this code snippet:

public boolean equals(Object o)
{
    if (o == null || !(o instanceof Line)) return false;
    Line other = (Line) o;
    return (origin == other.origin && direction == other.direction);
}

Should the 3 references to Line actually be Segment?
