ZCubeFileStatsCollector

class ZCubeFileStatsCollector extends AnyRef

ZCube file statistics collector. An object of this class can be used to collect ZCube statistics. The file statistics collection can be started by initializing an object of this class and calling updateStats on every new file seen. The number of ZCubes, number of files from matching cubes and number of unoptimized files are captured here.
