the class VectorFunction method visitSampledPeriods.

/**
 * Visits each of the sample periods and compiles a list of the double
 * values produced.
 */
private List<Double> visitSampledPeriods(ExprContext ctx, CommonExpressionVisitor visitor) {
    ExpressionParams params = visitor.getParams();
    ExpressionState state = visitor.getState();
    List<Double> values = new ArrayList<>();
    for (Period p : params.getSamplePeriods()) {
        state.setItemsFound(0);
        state.setItemValuesFound(0);
        Map<DimensionalItemObject, Object> valueMap = firstNonNull(params.getPeriodValueMap().get(p), Collections.emptyMap());
        Double value = visitWithValueMap(ctx, visitor, valueMap);
        if ((params.getMissingValueStrategy() == SKIP_IF_ANY_VALUE_MISSING && state.getItemValuesFound() < state.getItemsFound()) || (params.getMissingValueStrategy() == SKIP_IF_ALL_VALUES_MISSING && state.getItemsFound() != 0 && state.getItemValuesFound() == 0)) {
            value = null;
        }
        if (value != null) {
            values.add(value);
        }
    }
    return values;
