SYNOPSIS
       #include <stateout.h>

       Inherits sc::DescribedClass.

       virtual void put_header ()

       virtual int put_array_double (const double *p, int size)
       template<class T > int put (typename std::vector< T > &v)
	   Write an STL vector of data.
       void forget_references ()
	   Don't keep track of pointers to objects.
       void copy_references ()
	   If a reference to an object that has already been written is
	   encountered, copy it instead of generating a reference to the first
	   object.
       virtual int use_directory ()
	   Returns true if this object uses a directory.
       virtual void flush ()
	   Flush out any remaining data.
       int node_to_node () const
	   True if this is a node to node save/restore.
       virtual int tell ()
	   Returns the current position in the file.
       virtual void seek (int loc)
	   Set the current position in the file.
       virtual int seekable ()
	   Return non-zero if tell and seek do anything sensible.

Detailed Description
       Serializes objects that derive from SavableState.

       StateOut keeps track of pointers to data so that two references to the
       same piece of data do not result in that data being sent to the output
       device two times.

Member Function Documentation
   void sc::StateOut::copy_references ()
       If a reference to an object that has already been written is
       encountered, copy it instead of generating a reference to the first
       object. The directory will not be updated with new objects.

   void sc::StateOut::forget_references ()
       Don't keep track of pointers to objects. Calling this causes duplicated
       references to objects to be copied. The directory will not contain the
       forgotten objects.

   int sc::StateOut::node_to_node () const [inline]
       True if this is a node to node save/restore. This is necessary for
       classes that try to avoid saving databases to files that can otherwise
       be read in, but want to avoid reading the database from disk on all
       nodes.

   virtual int sc::StateOut::put (const char *, int) [virtual]
       Write the given array data. Size information is also saved. The data is
       allocated and read by the get(T*&) routines.

       Reimplemented in sc::MsgStateSend, and sc::StateOutText.

   virtual int sc::StateOut::put_array_char (const char * p, int size)
       [virtual]
       Put arrays of data. No size information is stored. This data is read by
       the get_array_T routines.

       Reimplemented in sc::StateOutText.

   virtual int sc::StateOut::putobject (const Ref< SavableState > &)
       [protected],  [virtual]
       This will prepare StateOut to output a pointer to data. It first checks
       to see if the data has already been saved. If it has, then a reference
       to this data is saved. Otherwise the object is written out.

       Reimplemented in sc::StateOutText.

   virtual int sc::StateOut::putstring (const char *) [virtual]
       This is like put except the length of the char array is determined by
       interpreting the character array as a character string.

       Reimplemented in sc::StateOutText.

   virtual void sc::StateOut::seek (int loc) [virtual]
       Set the current position in the file. The default implementation does
       nothing.

       Reimplemented in sc::StateOutBin.

   virtual int sc::StateOut::seekable () [virtual]
       Return non-zero if tell and seek do anything sensible. The default
       implementation returns 0.

       Reimplemented in sc::StateOutBin.

   virtual int sc::StateOut::tell () [virtual]
       Returns the current position in the file. The default implementation
       returns 0.

       Reimplemented in sc::StateOutBin.
