```
    Description copied from interface: DataPacker
    
    Transfer the data to the buffer. If you have already packed data to state * with DataPacker.determineLength(Object, PackerStore), you may transfer data from state * to targetBuffer. If not, you may directly transfer data to the targetBuffer.
    
    Specified by:
    
    writeDataToBuffer in interface DataPacker<T,T>
  - determineLength
```
default int determineLength(T data,
                            PackerStore store)
```
    Description copied from interface: DataPacker
    
    Pack the data and return the size of the data in bytes once packed. However, packing(converting to byte[]) and saving to store inside this method is optional. If your have primitives that can be efficiently copied to the buffers later in DataPacker.writeDataToBuffer(D, edu.iu.dsc.tws.api.comms.packing.PackerStore, int, int, int, java.nio.ByteBuffer), you may just return the byte size of data from this method.
    
    Specified by:
    
    determineLength in interface DataPacker<T,T>
    
    Parameters:
    
    data - the data (can be Integer, Object etc)
    
    store - A store to temporary store the serialized data, if you had to serialize data to determine length.
    
    Returns:
    
    the size of the packed data in bytes

```
    Description copied from interface: DataPacker
    
    Read the buffer and build the actual object. This method will be called multiple times per object until this method explicitly call ObjectBuilder.setFinalObject(Object) to set and mark the end of the current object
