Component::CallMethod

This method is used in C++ to call a method by name. User-defined components should use this to implement methods that can be triggered by a flowgraph connection.

Syntax

std::any CallMethod(shared_ptr<Component> caller, const WString& name, const std::vector\<std::any>& args)

Parameter	Description
caller	the component that triggered this method
name	the name of the method
args	list of function parameters

Returns

Returns any value.

Example

Here is an example of a component method that can be called by a flowgraph connection. The component code should check to make sure the supplied arguments are of the correct type.

virtual void SetHealth(const int healthvalue)
{
    this->health = healthvalue;
}

virtual std::any CallMethod(shared_ptr<Component> caller, const WString& name, const std::vector<std::any>& args)
{
    if (name == "SetHealth")
    {
        if (args.size() >= 1 and std::string(args[0].type().name()) == "int")
        {
            int arg0 = std::any_cast<int>(args[0]);
            SetHealth(arg0);
        }
    }
    return false;
}
