Example 11 with BinaryComparable

use of org.apache.hadoop.io.BinaryComparable in project presto by prestodb.

the class GenericHiveRecordCursor method parseStringFromPrimitiveWritableObjectValue.

    } else {
        throw new IllegalStateException("unsupported string field type: " + fieldValue.getClass().getName());
    }
    // create a slice view over the hive value and trim to character limits
    Slice value = trimStringToCharacterLimits(type, Slices.wrappedBuffer(hiveValue.getBytes(), 0, hiveValue.getLength()));
    // store a copy of the bytes, since the hive reader can reuse the underlying buffer
    return Slices.copyOf(value);
