Class LasPoint

java.lang.Object

org.tinfour.gis.las.LasPoint

public class LasPoint
extends Object

A simple data-holder class for transferring data from LAS file records. This class is intended for efficient use in applications that may process millions of records. Therefore, it is designed so that instances can be used and reused over and over again as temporary containers for data. Thus elements are exposed as public without accessors methods or other protections.

There is, however, no restriction on creating instances of this class. Depending on the requirements of the implementation, it may be completely reasonable to do so. However, when millions of points are to be processed, it will be advantageous to not create persistent instances.
