public abstract class TimeSeriesBlock

extends Persistent

Abstract base class for time series block. Progammer has to define its own block class derived from this class containign array of time series elements and providing getTicks() method to access this array. It is better no to initialize this array in constructor (because it will be also used when block will be loaded from the disk), but check in getTicks() method that array is null, and if so - create new array.
