Detailed Description

template<class X>
class ARCSTypeFactoryTemplate< X >

Template class to implement type factories.

This class adds two more methods to implement. Usually, in order to make a new type available to ARCS, one need to derive from this template and reimplement the methods getTypeName(), parse() and serialize(). If you use the automated process, the name of your derived class should conform to the following syntax: ARCSTypeFactoryTemplate_<yourtypeclass>. As an example here is partly how the type factory for integers is declared inside of ARCS.

class ARCSTypeFactory_int : public ARCSTypeFactoryTemplate<int>
{
public:
    virtual QString getTypeName() const { return "int"; }

protected:
    virtual int parse(QString s) { return s.toInt(); }
    virtual QString serialize(int obj) { return QString::number(obj);}
};
