Example 1 with CastFunction

use of io.confluent.ksql.execution.interpreter.terms.CastTerm.CastFunction in project ksql by confluentinc.

the class CastInterpreter method castToMapFunction.

    if (from.baseType() == SqlBaseType.MAP && to.baseType() == SqlBaseType.MAP) {
        final SqlMap fromMap = (SqlMap) from;
        final SqlMap toMap = (SqlMap) to;
        final CastFunction keyCastFunction = castFunction(fromMap.getKeyType(), toMap.getKeyType(), config);
        final CastFunction valueCastFunction = castFunction(fromMap.getValueType(), toMap.getValueType(), config);
        return o -> CastEvaluator.castMap((Map<?, ?>) o, keyCastFunction::cast, valueCastFunction::cast);
    }
    throw new KsqlException("Unsupported cast to " + to + ": " + from);
}

Example 2 with CastFunction

use of io.confluent.ksql.execution.interpreter.terms.CastTerm.CastFunction in project ksql by confluentinc.
