IntMaxCollector

public IntMaxCollector(IntValueStream param)

Method Detail

newData

public MaxCollector.IntMaxCollector.MaxData newData()

Description copied from class: ReductionDataCollector

A clean slate to start a new reduction.

Specified by:

newData in class ReductionDataCollector<MaxCollector.IntMaxCollector.MaxData>

Returns:

the new reduction data

max

public int max()

Returns the max value of the set data.

Returns:

the max

collect

public void collect()

Description copied from class: ReductionDataCollector

Collect the information from current Solr Document.

Overrides:

collect in class ReductionDataCollector<MaxCollector.IntMaxCollector.MaxData>

apply

protected void apply(MaxCollector.IntMaxCollector.MaxData 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<MaxCollector.IntMaxCollector.MaxData>

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<MaxCollector.IntMaxCollector.MaxData>

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. (FOR CLOUD)

Overrides:

setMergedData in class MaxCollector<MaxCollector.IntMaxCollector.MaxData>

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 MaxCollector<MaxCollector.IntMaxCollector.MaxData>

Parameters:

data - the collected data to compute a reduction for
