Example 1 with FlatBufferBuilder

use of org.apache.ratis.thirdparty.com.google.flatbuffers.FlatBufferBuilder in project incubator-ratis by apache.

the class ClientFlat method execFlatClient.

            FlatBufferBuilder builder = new FlatBufferBuilder();
            bf.position(0).limit(bf.capacity());
            // create string of the message data
            // the datacopy happens here, significant CPU time spent.
            int dataOff = builder.createString(bf);
            // Use flatbuffers generated message builder.
            int off = TransferMsg.createTransferMsg(builder, partId, dataOff);

    } catch (Exception e) {
        System.out.println(e);
    }
    requestObserver.onCompleted();
    Thread.sleep(1000 * 100);
    if (recv[0] == partId) {
