SIM_Solver, SIM_data and memory cache

[iaiotom]

Hello,

I'm quite new to HDK so apologies if this is a stupd question. I'm writing a new SIM_Solver with same custom SIM_Data. There is no geometry data involved but only custom data. When I simulate for the first time my scene, the solver is called correctly at each frame and it starts to cache te result in memory. And here I get lost. I can't find which method it uses the cache the data in memory. All the examples in the devkit are using geometry data so I think houdini caches the geoemtry in memory. But with my custom data what I need to do to cache it in memory?

 

Thank you

Alan

 

This is the declaration of my sim data:

class SIM_AgentGroup : public SIM_Data,
    public SIM_OptionsUser
{
public:

    AtomsPtr<Atoms::AgentGroup>& agentGroup();

   const AtomsPtr<Atoms::AgentGroup>& agentGroup() const;

    void printOptions();

    SOP_Node* getInputSopNode();

protected:

    explicit SIM_AgentGroup(const SIM_DataFactory *factory);

    virtual ~SIM_AgentGroup();

    virtual void initializeSubclass();
    virtual void makeEqualSubclass(const SIM_Data *source);

private:

    static const SIM_DopDescription *getSIM_AgentGroupDopDescription();

    DECLARE_STANDARD_GETCASTTOTYPE();
    DECLARE_DATAFACTORY(SIM_AgentGroup,
    SIM_Data,
        "Agent Properties",
        getSIM_AgentGroupDopDescription());

private:

    AtomsPtr<Atoms::AgentGroup> m_agentGroup;
};
