Hi all,
As mentioned some days ago, I need some help on c++.
I want to create a new class ClumpTemplate. When it is constructed it
just should store some informations:
- an id for the template
- number of clump members (numCM)
- relative radii list (length == numCM)
- relative postions list (length == numCM)
For initiation the length (numCM) is unknown. This is what I have done
until know:
//######code for ClumpTemplate.hpp:
#pragma once
class ClumpTemplate {
public:
typedef const int id_ct;
typedef const shared_ptr<ClumpTemplate> ct;
ClumpTemplate ct;
int numCM; //number of clump members
Real[] rad; //relative radii list
Vector3r[] pos; //rel. position vector list
int ClumpTemplate(); //returns id
};
//######code for ClumpTemplate.cpp:
#include <yade/core/ClumpTemplate.hpp>
class ClumpTemplate;
// set id to -1, if not constructed yet
const ClumpTemplate::id_ct ClumpTemplate::ID_NONE=ClumpTemplate::id_ct(-1);
int ClumpTemplate::ClumpTemplate(){
int id = this.id_ct + 1;
return id;
}
//####compiler says:
[ 14%] Built target support
[ 15%] Building CXX object CMakeFiles/core.dir/core/ClumpTemplate.cpp.o
