public interface DelayableLittleEndianOutput
extends LittleEndianOutput

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 createDelayedOutput(int) to reserve two bytes of the output for the 'ushort size' header field. The delayed output can be written at any stage.
