Type Members

1. case class BinnedTime(bin: Short, offset: Long) extends Product with Serializable

   

   Represents a time by an offset into a binned bucket.

   Represents a time by an offset into a binned bucket. The bin represents days, weeks, months or years since the java epoch. The offset represents milliseconds, seconds, or hours into that bin.

   Times can be partitioned based on four periods:

   TimePeriod.Day bin => day offset => milliseconds max date => 2059/09/18

   TimePeriod.Week bin => week offset => seconds max date => 2598/01/04

   TimePeriod.Month bin => month offset => seconds max date => 4700/08/31

   TimePeriod.Year bin => year offset => minutes max date => 34737/12/31

   bin

   number of time periods from the java epoch

   offset

   precise offset into the specific time period

2. trait NormalizedDimension extends AnyRef

   

   Maps a double within a known range to an Int in [0, bins)

3. class S2SFC extends SpaceFillingCurve

   

   S2 space-filling curve

4. trait SpaceFillingCurve extends AnyRef

   

5. trait SpaceTimeFillingCurve extends AnyRef

   

6. class XZ2SFC extends AnyRef

   

   Extended Z-order curve implementation used for efficiently storing polygons.

   Extended Z-order curve implementation used for efficiently storing polygons.

   Based on 'XZ-Ordering: A Space-Filling Curve for Objects with Spatial Extension' by Christian Böhm, Gerald Klump and Hans-Peter Kriegel

7. class XZ3SFC extends AnyRef

   

   Extended Z-order curve implementation used for efficiently storing polygons.

   Extended Z-order curve implementation used for efficiently storing polygons.

   Based on 'XZ-Ordering: A Space-Filling Curve for Objects with Spatial Extension' by Christian Böhm, Gerald Klump and Hans-Peter Kriegel, expanded to 3 dimensions

8. class Z2SFC extends SpaceFillingCurve

   

   z2 space-filling curve

9. class Z3SFC extends SpaceTimeFillingCurve

   

   Z3 space filling curve

10. class LegacyYearXZ3SFC extends XZ3SFC

    

    XZ3SFC with a legacy, incorrect max time value of 52 weeks.

    XZ3SFC with a legacy, incorrect max time value of 52 weeks. The max value is kept the same to ensure that index keys and query ranges are consistent. Any dates that exceed the original max time will be dropped into the last time bin, potentially degrading results for the last day or two of the year.
