NAME

       branch - a parameter-dependent sequence of field

DESCRIPTION

       Stores a field sequence together with its associated parameter value: a branch variable represents a pair (t,uh(t)) for a specific value of
       the parameter t.  Applications concern time-dependent problems and continuation methods.

       This class is convenient for file inputs/outputs and building graphical animations.

EXAMPLES

       Coming soon...

LIMITATIONS

       This class is under development.

       The branch class store pointers on field class without reference counting. Thus, branch automatic variables cannot  be  returned  by  func-
       tions. branch variable are limited to local variables.

IMPLEMENTATION

       template <class T, class M = rheo_default_memory_model>
       class branch_basic : public std::vector<std::pair<std::string,field_basic<T,M> > > {
       public :
       // typedefs:

	 typedef std::vector<std::pair<std::string,field_basic<T,M> > >     base;
	 typedef typename base::size_type				    size_type;

       // allocators:

	 branch_basic ();
	 branch_basic (const std::string& parameter_name, const std::string& u0);
	 branch_basic (const std::string& parameter_name, const std::string& u0, const std::string& u1);
	 ~branch_basic();

       // accessors:

	 const T&  parameter () const;
	 const std::string& parameter_name () const;
	 size_type     n_value () const;
	 size_type     n_field () const;

       // modifiers:

	 void set_parameter (const T& value);
	 void set_range (const std::pair<T,T>& u_range);

       // input/output:

	 // get/set current value
	 __obranch<T,M> operator()  (const T& t, const field_basic<T,M>& u0);
	 __obranch<T,M> operator()  (const T& t, const field_basic<T,M>& u0, const field_basic<T,M>& u1);

	 __iobranch<T,M> operator() (T& t, field_basic<T,M>& u0);
	 __iobranch<T,M> operator() (T& t, field_basic<T,M>& u0, field_basic<T,M>& u1);

	 __branch_header<T,M>	      header ();
	 __const_branch_header<T,M>   header () const;
	 __const_branch_finalize<T,M> finalize () const;
