All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`Data`	`createNext(DataHead dataHead, java.nio.ByteBuffer buf)`	Factory method to create a Data.
`byte[]`	`read()`	TODO: should the return type be ByteBuffer ?? Return part's partial data.
`int`	`size()`	size of the chunk given by the parser
`long`	`writeTo(DataFile file)`	Write this partial data to a file

- Method Detail
  - size
```
int size()
```
    size of the chunk given by the parser
    
    Returns:
    
    size of the chunk
  - read
```
byte[] read()
```
    TODO: should the return type be ByteBuffer ?? Return part's partial data. The data is read only.
    
    Returns:
    
    a byte array which contains {#size()} bytes. The returned array may be larger than {#size()} bytes and contains data from offset 0.
  - writeTo
```
long writeTo(DataFile file)
```
    Write this partial data to a file
    
    Parameters:
    
    file - to which the data needs to be written
    
    Returns:
    
    file pointer before the write operation(at which the data is written from)
  - createNext
```
Data createNext(DataHead dataHead,
                java.nio.ByteBuffer buf)
```
    Factory method to create a Data. The implementation could be file based one or memory based one.
    
    Parameters:
    
    dataHead - start of the linked list of data objects
    
    buf - contains partial content for a part
    
    Returns:
    
    Data
