 @NotNull
 @NotNull Chunk<? extends Values>[] valueChunkArr,
 LongChunk<? extends Values> tsChunk,
 int len)

Overrides:

accumulateCumulative in class BaseDoubleUpdateByOperator.Context

 @NotNull Chunk<? extends Values>[] valueChunks)

Overrides:

setValueChunks in class BaseDoubleUpdateByOperator.Context

isValueValid

public boolean isValueValid(long atKey)

Overrides:

push

public void push(int pos,
 int count)

Description copied from class: UpdateByOperator.Context

Add values to the operators current data set

Specified by:

push in class UpdateByOperator.Context

Parameters:

pos - the index in the associated chunk where this value can be found. Depending on the usage, might be a values chunk (for cumulative operators) or an influencer values chunk (for windowed). It is the task of the operator to pull the data from the chunk and use it properly

count - the number of items to push from the chunk
