    Parameters:
    
    table - table to write
    
    storagePolicy - policy for acquiring byte array scratch buffers
    
    allowSignedByte - if true, bytes written as FITS signed bytes (TZERO=-128), if false bytes written as signed shorts
    
    Throws:

  - set64BitMode
```
public void set64BitMode(boolean useQ)
```
    Sets whether this serializer should use the 'P' descriptor (32-bit addressing into the heap) or the 'Q' descriptor (64-bit addressing into the heap) for variable-length array columns. Normally Q is only used if the heap is larger than 2^31.
    
    Parameters:
    
    useQ - true for Q, false for P
  - getHeader
