Detailed Description

A set of 2D linestring features, also known as "polylines." Each linestring is basically a simple set of 2D points.

void vtFeatureSetLineString::Reserve (  int  iNum  )  [virtual]

If you know how many entities you will be adding to this FeatureSet, is it more efficient to reserve space for that many. Implements vtFeatureSet.
