Example 1 with ResultMessage

use of org.apache.cassandra.transport.messages.ResultMessage in project cassandra by apache.

the class QueryProcessor method executeInternalWithNow.

/**
 * A special version of executeLocally that takes the time used as "now" for the query in argument.
 * Note that this only make sense for Selects so this only accept SELECT statements and is only useful in rare
 * cases.
 */

    Prepared prepared = prepareInternal(query);
    assert prepared.statement instanceof SelectStatement;

    ResultMessage result = select.executeInternal(internalQueryState(), makeInternalOptions(prepared.statement, values), nowInSec, queryStartNanoTime);
    assert result instanceof ResultMessage.Rows;
