Usage

From source file:org.jpmml.evaluator.functions.AggregateFunction.java

@Override

    StorelessUnivariateStatistic statistic = createStatistic();

    DataType dataType = null;//from w  w  w  . j  a  va  2s . c o m

    // "Missing values in the input to an aggregate function are simply ignored"
    Iterable<FieldValue> values = Iterables.filter(arguments, Predicates.notNull());
    for (FieldValue value : values) {
        statistic.increment((value.asNumber()).doubleValue());

        if (dataType != null) {
            dataType = TypeUtil.getResultDataType(dataType, value.getDataType());
        } else

        {

    }

    if (statistic.getN() == 0) {
        throw new InvalidResultException(null);
