FastTimeSeriesCollection is appropriate for a fixed time range; for real-time applications this subclass adds the ability to append new data and discard the oldest. In this class, the arrays used in FastTimeSeriesCollection become FIFO's. NOTE:As presented here, all data is assumed >= 0, an assumption which is embodied only in methods associated with interface RangeInfo.<P><P><DL><DT><B>Author:</B></DT> <DD>Irv Thomae.</DD><DT><B>See
