Detailed Description

Helper class due to PIMPL excess.

This class is deisgned to work within vtkXMLWriter. It store a position in a file (unsigned long) and associate a offset in the file. This is usefull when writing TimeStep XML file when you want to forward the same offset from the AppendData section on every entry in let say <Points> definition Example:

 <Points>
   <DataArray type="Float32" TimeStep="0" format="appended" offset="268" />
   <DataArray type="Float32" TimeStep="1" format="appended" offset="268" />
   ...
 </Points>
 

Therefore data is only stored once in the XML file. At read time the offset value is stored to determine whenever we need to read data (ie when offset different from previously stored offset)

Warning:

Do not include this file in a header file, it will break PIMPL convention
