Examples of org.apache.cassandra.utils.MD5Digest

org.apache.cassandra.utils.MD5Digest
The result of the computation of an MD5 digest. A MD5 is really just a byte[] but arrays are a no go as map keys. We could wrap it in a ByteBuffer but: 1. MD5Digest is a more explicit name than ByteBuffer to represent a md5. 2. Using our own class allows to use our FastByteComparison for equals.

        execute("INSERT INTO %s.single_clustering (a, b, c) VALUES (0, 0, 0)");
        execute("INSERT INTO %s.single_clustering (a, b, c) VALUES (0, 1, 0)");
        execute("INSERT INTO %s.single_clustering (a, b, c) VALUES (0, 2, 0)");


        MD5Digest id = prepare("SELECT * FROM %s.single_clustering WHERE a=0 AND (b) > ?");
        UntypedResultSet results = executePrepared(id, options(tuple(0)));
        assertEquals(2, results.size());
        checkRow(0, results, 0, 1, 0);
        checkRow(1, results, 0, 2, 0);
