Example 1 with DruidDoublePredicate

use of org.apache.druid.query.filter.DruidDoublePredicate in project druid by druid-io.

the class ValueMatchers method makeDoubleValueMatcher.

/**
 * Creates a predicate-based {@link ValueMatcher} for a double-typed selector.
 *
 * @param selector         column selector
 * @param predicateFactory predicate to match
 */
public static ValueMatcher makeDoubleValueMatcher(final BaseDoubleColumnValueSelector selector, final DruidPredicateFactory predicateFactory) {
    final DruidDoublePredicate predicate = predicateFactory.makeDoublePredicate();
    return new ValueMatcher() {

        @Override
        public boolean matches() {
            if (selector.isNull()) {
                return predicate.applyNull();
            }
            return predicate.applyDouble(selector.getDouble());
        }

        @Override
        public void inspectRuntimeShape(RuntimeShapeInspector inspector) {
            inspector.visit("selector", selector);
            inspector.visit("predicate", predicate);
        }
    };
}

Example 2 with DruidDoublePredicate

use of org.apache.druid.query.filter.DruidDoublePredicate in project druid by druid-io.

the class DoubleVectorValueMatcher method makeMatcher.

    final DruidDoublePredicate predicate = predicateFactory.makeDoublePredicate();
    return new BaseVectorValueMatcher(selector) {

        final VectorMatch match = VectorMatch.wrap(new int[selector.getMaxVectorSize()]);

            final double[] vector = selector.getDoubleVector();
            final int[] selection = match.getSelection();
            final boolean[] nulls = selector.getNullVector();
            final boolean hasNulls = canHaveNulls && nulls != null;
            int numRows = 0;
            for (int i = 0; i < mask.getSelectionSize(); i++) {
