Examples with SqlOperatorConversion org.apache.druid.sql.calcite.expression.SqlOperatorConversion used on opensource projects

Example 1 with SqlOperatorConversion

use of org.apache.druid.sql.calcite.expression.SqlOperatorConversion in project druid by druid-io.

the class DruidOperatorTable method lookupOperatorOverloads.

@Override
public void lookupOperatorOverloads(final SqlIdentifier opName, final SqlFunctionCategory category, final SqlSyntax syntax, final List<SqlOperator> operatorList, final SqlNameMatcher nameMatcher) {
    if (opName == null) {
        return;
    }
    if (opName.names.size() != 1) {
        return;
    }
    final OperatorKey operatorKey = OperatorKey.of(opName.getSimple(), syntax);
    final SqlAggregator aggregator = aggregators.get(operatorKey);
    if (aggregator != null) {
        operatorList.add(aggregator.calciteFunction());
    }
    final SqlOperatorConversion operatorConversion = operatorConversions.get(operatorKey);
    if (operatorConversion != null) {
        operatorList.add(operatorConversion.calciteOperator());
    }
    final SqlOperator convertletOperator = CONVERTLET_OPERATORS.get(operatorKey);
    if (convertletOperator != null) {
        operatorList.add(convertletOperator);
    }
}

Example 2 with SqlOperatorConversion

use of org.apache.druid.sql.calcite.expression.SqlOperatorConversion in project druid by druid-io.

    final List<SqlOperator> retVal = new ArrayList<>();
    for (SqlAggregator aggregator : aggregators.values()) {
        retVal.add(aggregator.calciteFunction());
    }
    for (SqlOperatorConversion operatorConversion : operatorConversions.values()) {
        retVal.add(operatorConversion.calciteOperator());
    }
    retVal.addAll(DruidConvertletTable.knownOperators());
    return retVal;
