getAggregatedValueType

public FieldSpec.DataType getAggregatedValueType()

Description copied from interface: ValueAggregator

Returns the data type of the aggregated value.

Specified by:

getAggregatedValueType in interface ValueAggregator<byte[],org.apache.datasketches.tuple.Sketch<org.apache.datasketches.tuple.aninteger.IntegerSummary>>

getInitialAggregatedValue

public org.apache.datasketches.tuple.Sketch<org.apache.datasketches.tuple.aninteger.IntegerSummary> getInitialAggregatedValue(byte[] rawValue)

Description copied from interface: ValueAggregator
