  • Constructor Details

    • FieldSortedListTrimmer

      public FieldSortedListTrimmer(int neighborsSize)
      Create a new cache with the given neighbors size and data.
      Parameters:
      neighborsSize - size of the list returned from getNeighborsSubList(FieldAbsoluteDate, List).

  • Method Details

    • getNeighborsSize

      public int getNeighborsSize()
      Get size of the list returned from getNeighborsSubList(FieldAbsoluteDate, List).
      Returns:
      size of the list returned from getNeighborsSubList(FieldAbsoluteDate, List)

    • getNeighborsSubList

      public <T extends FieldTimeStamped<K>, K extends CalculusFieldElement<K>> List<T> getNeighborsSubList(FieldAbsoluteDate<K> central, List<T> data)
      Get the entries surrounding a central date.

      If the central date is well within covered range, the returned array will be balanced with half the points before central date and half the points after it (depending on n parity, of course). If the central date is near the boundary, then the returned array will be unbalanced and will contain only the n earliest (or latest) entries. A typical example of the later case is leap seconds cache, since the number of leap seconds cannot be arbitrarily increased.

      Type Parameters:
      T - the type of data
      K - the type of the field elements
      Parameters:
      central - central date
      data - complete list of entries (must be chronologically sorted)
      Returns:
      entries surrounding the specified date (sublist of data)
