NumberByLongAggregator

public NumberByLongAggregator(Comparator<? super Long> p_comparator)

Create an aggregator for numerical values.

If a comparator is given "category" values for which this comparator returns a value of zero are considered equal.

Parameters:

p_comparator - A comparator for long values, or null.

Method Detail

getAggregatedValues

public NumberByLongAggregator.SortableSumByLongAggregatorBucketList getAggregatedValues()

Get an ascendingly ordered list of aggregated values.

Specified by:

getAggregatedValues in class AbstractNumberAggregator<Long,SumByLongAggregatorBucket>

Returns:

The list of aggregated values.

add

public void add(Number p_num,
                String p_strRow,
                Number p_value,
                String p_strSingleId)

Add an observation.

Parameters:

p_num - The numeric "category" value.

p_strRow - The row value.

p_value - The value.

p_strSingleId - A an identifier that is being stored as long as there is exactly one such identifier for a group (normally a record ID).
