Interface CentroidManager<T>

Type Parameters:

T - The type of item that is used to represent a centroid.

All Known Implementing Classes:

CentroidManagerGeoWave

public interface CentroidManager<T>

Manage centroids created per batch and per group of analytic processes. There can be multiple groups per batch. A group is loosely interpreted as a set of item geometries under analysis. The sets can be defined by shared characteristics.
