Class LineString

  • All Implemented Interfaces:
    java.io.Serializable
    public final class LineString
extends EField
    Contains two or more Positions used to define a "line". The reason for the quotes is the the points may form a figure which may cross itself, form a closed polygon, or define a curve. It does not have to define a straight line.
