Description

This module gathers all methods provided to handle atoms with no alternate location identification and occupancy factor different from 1. An occupancy policy must be a class of the following type:

template <class Line_format>
struct Occupancy_policy_concept{
  //check whether an atom can directly be added to a system. 
  //It returns -1 if not, and the number of the system otherwise.
  //Line_format must provide  similar functionalities to ESBTL::PDB::Line_format.
  //line is a line of a molecular data file representing an atom.
  //system_index is the index of the system the line should be added (provided by the selector).
  int add_or_postpone(const Line_format& line_format,const std::string& line,int system_index) const{ ... }
  
  //This function is called by the builder when the whole file have been read.
  //Potential atom that have not already been inserted can be. The integer returned is
  //the number of atoms added.
  template <class Builder> int finalize(Builder&) const { ... }
};
