Detailed Description

template<class E, typename T>
class dynamicgraph::command::Setter< E, T >

Command that calls a parameter setter function

This class is templated by a type E deriving from entity and a type T of data.

Let us assume that class E has a private member of type T and a public setter function for this member:

class E : public Entity
{
public:
  E (const std::string& inName) : Entity(inName) {}
  void setParameter(const T& parameter) {parameter_ = parameter;}
private:
  T parameter_;
};

Then the command defined by:

E entity("MyEntity");
Setter<E,T> command(entity, &E::getParameter)

sets the value of entity.parameter_ upon invocation.

Note

• T should be a type supported by class Value,
• prototype of E::setParameter should be exactly as specified in this example.
