branch

parameter-dependent sequence of field

Description

The branch class 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 for building animations. It extends to multi-field sequences, such as (t,uh(t),ph(t)), up to an arbitrarily number of fields. See also the branch unix command for running animations.

Implementation

This documentation has been generated from file main/lib/branch.h

The branch class is simply an alias to the branch_basic class

typedef branch_basic<Float> branch;

The branch_basic class provides an interface to a n-uplet of fields together with a parameter value:

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();
  branch_basic (const branch_basic<T,M>&);
  branch_basic<T,M>& operator= (const branch_basic<T,M>&);
 
  template <typename... Args>
  branch_basic(const std::string& parameter, Args... names);
 
// 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_name (const std::string& name);
  void set_parameter (const T& value);
  void set_range (const std::pair<T,T>& u_range);

};
template <class T, class M> idiststream& operator>> (idiststream&, branch_basic<T,M>&);
template <class T, class M> odiststream& operator<< (odiststream&, const branch_basic<T,M>&);
