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.
