Member Function Documentation

◆ Component()

jevois::Component::Component

Constructor.

The standard way to create a component is via Component::addSubComponent() or Manager::addComponent(), rather than constructing them by hand. Components constructed via the constructor (e.g., calling operator new) will not be attached to a Component hierarchy. It is recommended that derived components also have an instance constructor argument and pass it down to the base Component class, to allow complex systems with several instances of a same Component. In fact, for most components, the inherited constructor is appropriate:

class MyComp : public jevois::Component
{
public:
// Inherited constructor
// Virtual destructor for safe inheritance
virtual ~MyComp();
};
