Class BUCKETIZECALENDAR

java.lang.Object

io.warp10.script.NamedWarpScriptFunction

io.warp10.script.functions.BUCKETIZECALENDAR

All Implemented Interfaces:

WarpScriptStackFunction

public class BUCKETIZECALENDAR
extends NamedWarpScriptFunction
implements WarpScriptStackFunction

Bucketizes some GTS instances using a bucketduration rather than a bucketspan. The tick of the resulting buckets will be their index (number of bucketduration since Unix Epoch). The goal is to make possible to apply functions for bucketized series on a series with bucket of irregular calendar bucket span. To restore timestamp for ticks, there is UNBUCKETIZE.CALENDAR.
