public StringMinCollector(StringValueStream param)

Method Detail

newData

public MinCollector.StringMinCollector.MinData newData()

Description copied from class: ReductionDataCollector

A clean slate to start a new reduction.

Specified by:

newData in class ReductionDataCollector<MinCollector.StringMinCollector.MinData>

Returns:

the new reduction data

min

public String min()

Returns the min value of the set data.

Returns:

the min

collect

public void collect()

Description copied from class: ReductionDataCollector

Collect the information from current Solr Document.

Overrides:

collect in class ReductionDataCollector<MinCollector.StringMinCollector.MinData>

apply

protected void apply(MinCollector.StringMinCollector.MinData data)

Description copied from class: ReductionDataCollector

Apply the collected info to the given reduction data. Should always be called after a ReductionDataCollector.collect() call.

Specified by:

apply in class ReductionDataCollector<MinCollector.StringMinCollector.MinData>

Parameters:

data - reduction data to apply collected info to

submitReservations

public void submitReservations(Consumer<ReductionDataReservation<?,?>> consumer)

Description copied from class: ReductionDataCollector

Submits the data reservations needed for this data collector.

Specified by:

submitReservations in class ReductionDataCollector<MinCollector.StringMinCollector.MinData>

Parameters:

consumer - the consumer which the reservations are submitted to

setMergedData

public void setMergedData(ReductionData data)

Description copied from class: ReductionDataCollector

Finalize the reduction with the merged data stored in the parameter. Once the reduction is finalized, the ReductionFunctions that use this data collector act like regular AnalyticsValue classes that can be accessed through their get<value-type> methods.

Overrides:

setMergedData in class MinCollector<MinCollector.StringMinCollector.MinData>

Parameters:

data - the merged data to compute a reduction for

setData

public void setData(ReductionData data)

Description copied from class: ReductionDataCollector

Finalize the reduction with the collected data stored in the parameter. Once the reduction is finalized, the ReductionFunctions that use this data collector act like regular AnalyticsValue classes that can be accessed through their get<value-type> methods.

(FOR SINGLE-SHARD)

Overrides:

setData in class MinCollector<MinCollector.StringMinCollector.MinData>

Parameters:

data - the collected data to compute a reduction for
