Method Details

buildEventFromDelta

E buildEventFromDelta(long timeFrom,
 long timeTo,
 T aggregation,
 double currentSizeIncrement,
 double targetSizeIncrement)

Builds a Bookmap event for a single historical block from a delta aggregation, using the snapshot state accumulated from previous blocks.

Parameters:

timeFrom - start of the block's time window, in nanoseconds (inclusive)

timeTo - end of the block's time window, in nanoseconds (exclusive)

aggregation - the block's delta aggregation

currentSizeIncrement - the size increment the stored data is in

targetSizeIncrement - the size increment the produced event should be in

Returns:

the event for this block; its timeFrom/timeTo should be the given window
