Examples of org.apache.poi.util.DelayableLittleEndianOutput

org.apache.poi.util.DelayableLittleEndianOutput
Implementors of this interface allow client code to 'delay' writing to a certain section of a data output stream.
A typical application is for writing BIFF records when the size is not known until well after the header has been written. The client code can call {@link #createDelayedOutput(int)}to reserve two bytes of the output for the 'ushort size' header field. The delayed output can be written at any stage. @author Josh Micich

      _dataSizeOutput = dleo.createDelayedOutput(2);

      _out = out;
