Method Details

selectedMayContainUnseenGroups

public void selectedMayContainUnseenGroups(SeenGroupIds seenGroupIds)

Description copied from interface: GroupingAggregatorFunction

Call this to signal to the aggregation that the selected parameter that's passed to GroupingAggregatorFunction.evaluateIntermediate(org.elasticsearch.compute.data.Block[], int, org.elasticsearch.compute.data.IntVector) or GroupingAggregatorFunction.evaluateFinal(org.elasticsearch.compute.data.Block[], int, org.elasticsearch.compute.data.IntVector, org.elasticsearch.compute.aggregation.GroupingAggregatorEvaluationContext) may reference groups that haven't been seen. This puts the underlying storage into a mode where it'll track which group ids have been seen, even if that increases the overhead.

Specified by:

selectedMayContainUnseenGroups in interface GroupingAggregatorFunction

prepareProcessRawInputPage

public GroupingAggregatorFunction.AddInput prepareProcessRawInputPage(SeenGroupIds seenGroupIds,
 Page page)

Description copied from interface: GroupingAggregatorFunction

Prepare to process a single page of raw input.

This should load the input Blocks and check their types and select an optimal path and return that path as an GroupingAggregatorFunction.AddInput.

Specified by:

prepareProcessRawInputPage in interface GroupingAggregatorFunction

intermediateBlockCount

public int intermediateBlockCount()

Description copied from interface: GroupingAggregatorFunction

The number of blocks used by intermediate state.

Specified by:

intermediateBlockCount in interface GroupingAggregatorFunction

addIntermediateInput

public void addIntermediateInput(int positionOffset,
 IntArrayBlock groups,
 Page page)

Description copied from interface: GroupingAggregatorFunction

Add data produced by GroupingAggregatorFunction.evaluateIntermediate(org.elasticsearch.compute.data.Block[], int, org.elasticsearch.compute.data.IntVector).

Specified by:

addIntermediateInput in interface GroupingAggregatorFunction

addIntermediateInput

public void addIntermediateInput(int positionOffset,
 IntBigArrayBlock groups,
 Page page)

Description copied from interface: GroupingAggregatorFunction

Add data produced by GroupingAggregatorFunction.evaluateIntermediate(org.elasticsearch.compute.data.Block[], int, org.elasticsearch.compute.data.IntVector).

Specified by:

addIntermediateInput in interface GroupingAggregatorFunction

addIntermediateInput

public void addIntermediateInput(int positionOffset,
 IntVector groups,
 Page page)

Description copied from interface: GroupingAggregatorFunction

Add data produced by GroupingAggregatorFunction.evaluateIntermediate(org.elasticsearch.compute.data.Block[], int, org.elasticsearch.compute.data.IntVector).

Specified by:

addIntermediateInput in interface GroupingAggregatorFunction

evaluateIntermediate

public void evaluateIntermediate(Block[] blocks,
 int offset,
 IntVector selected)

Description copied from interface: GroupingAggregatorFunction

Build the intermediate results for this aggregation.

Specified by:

evaluateIntermediate in interface GroupingAggregatorFunction

Parameters:

selected - the groupIds that have been selected to be included in the results. Always ascending.

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface org.elasticsearch.core.Releasable

evaluateFinal

public void evaluateFinal(Block[] blocks,
 int offset,
 IntVector selected,
 GroupingAggregatorEvaluationContext evalContext)

Description copied from interface: GroupingAggregatorFunction

Build the final results for this aggregation.

Specified by:

evaluateFinal in interface GroupingAggregatorFunction

Parameters:

selected - the groupIds that have been selected to be included in the results. Always ascending.

toString

public String toString()

Overrides:

toString in class Object
