Interface AuxPointStrategy

All Known Implementing Classes:

Closest, Earlier, Later

public interface AuxPointStrategy

An AuxPointStrategy defines which point from a given TreeSet should be returned. You could also interpolate between two results and return a new interpolated Point. This can return null if the data doesn't exist in this context. For example if the File from which the data was read does not contain a valid point for that eventTimeStamp.

This interface also defines convenience functions for creating these strategy objects.

Method Detail

getPointFromTreeSet

AuxPoint getPointFromTreeSet(TreeSet<AuxPoint> set,
                             ZonedDateTime eventTimeStamp)

Parameters:

set - the set from which to get the points

eventTimeStamp - the timestamp for which you want the auxiliary data

Returns:

an AuxPoint according to the concrete strategy implementation.

Closest

static AuxPointStrategy Closest()

Convenience method to create Strategy object

Returns:

strategy to get the closest AuxPoint in Time.

Earlier

static AuxPointStrategy Earlier()

Convenience method to create Strategy object

Returns:

strategy to get the closest AuxPoint that comes earlier in Time.

Later

static AuxPointStrategy Later()

Convenience method to create Strategy object

Returns:

strategy to get the closest AuxPoint that comes later in Time.
