function getPoint( 
   index : number(Integer)
) : (Any);

var resultVar = instanceOfPointCollection.getPoint(number(Integer));

Parameters

index

The zero-based index of the point to return.

This function returns a copy of the given point in the collection. Because the returned value is a copy, changing the x or y values of the returned Point will have no effect on the point in the collection. This behavior helps to guarantee that a PointCollection object raises the pointChanged event at the appropriate times.
