In-Depth Information
provide a method implementation. The following interface
Volume
includes a default
method implementation for the
calculateVolume
method:
public interface Volume {
/**
* Calculate pool volume given depth values and
measurement values. For
* a pool with variable depth, the minDepth should be
depthValues[0], and
* the maxDepth should be passed as depthValues[1].
*
* This interface can accept multiple measurement
values, but it expects
* measurementValues[0] == length, or
measurementValues[0] == radius
* measurementValues[1] == width
* @param depthValues
* @param measurementValues
* @return
