> Several methods in the current XDR class have ambiguous semantics. For 
> example, Size() returns the actual size of internal byte array. The actual 
> size of current buffer, is also affected by read requests, which pull data 
> out of the buffer.
> These ambiguous semantics makes removing redundant copies on the NFS paths 
> difficult.
> This JIRA proposes to decompose the responsibilities of XDR into two separate 
> class: XDRReader and XDRWriter. The overall designs should closely follow 
> Java's *Reader / *Writer classes.
