Description

Represents a collection of waypoints used with GreatArc vehicles

Object Model

Public Methods

Add	Adds a new element to the collection.
Contains	Determines whether the collection contains the waypoint at the specified time.
IndexOf	Determines whether the collection contains the specified waypoint and returns an index of existing waypoint. The index < 0="" indicates="" the="" way="" point="" is="" not="" in="" the="" collection.="">
RemoveAll	Removes all elements from the collection.
RemoveAt	Removes an element from the collection using specified index.
ToArray	Returns a two-dimensional array that contains the way points. Each sub-array represents a waypoint. The order of the elements is Time, Latitude, Longitude, Altitude,Speed,Acceleration,TurnRadius

Public Properties

Count	Returns the number of elements in a collection.
Item	Given an index, returns an element in the collection.

Example
