public ByteChunkDeferred(String namePrefix,
                         int chunkId,
                         Types.MAPIType type)

    Creates a Byte Stream Chunk, with the specified type.
- Method Detail
  - readValue
```
public void readValue(DocumentNode node)
```
    Links the chunk to a document
    
    Parameters:
    
    node - the document node
  - readValue
```
public void readValue(InputStream value)
               throws IOException
```
    Description copied from class: Chunk
    
    Reads the value of this chunk using an InputStream
    
    Overrides:
    
    readValue in class ByteChunk
    
    Throws:
    
    IOException
  - writeValue
```
public void writeValue(OutputStream out)
                throws IOException
```
    Description copied from class: Chunk
    
    Writes the value of this chunk back out again.
    
    Overrides:
    
    writeValue in class ByteChunk
    
    Throws:
    
    IOException
  - getValue
```
public byte[] getValue()
```
    Get bytes directly.
    
    Overrides:
    
    getValue in class ByteChunk
  - setValue
```
public void setValue(byte[] value)
```
    Set bytes directly.
    updating the linked document node/msg file directly would be unexpected, so we remove the link and act as a ByteChunk from then
    
    Overrides:
    
    setValue in class ByteChunk
