Detailed Description

This class can be used to define new forces.

To use it, create a class that extends Force::Custom::Implementation. You can then create an instance of it and pass it to the Force::Custom constructor:

 Force::Custom myForce(forces, new MyForceImplementation());
 

Alternatively, you can create a subclass of Force::Custom which creates the Implementation itself:

 class MyForce : public Force::Custom {
 public:
   MyForce(GeneralForceSubsystem& forces) : Force::Custom(forces, new MyForceImplementation()) {
   }
 }
 

This allows a user to simply write

 MyForce(forces);
 

and not worry about implementation classes or creating objects on the heap. If you do this, your Force::Custom subclass must not have any data members or virtual methods. If it does, it will not work correctly. Instead, store all data in the Implementation subclass.

Constructor & Destructor Documentation

Custom	(	GeneralForceSubsystem &	forces,
		Implementation *	implementation
	)

Create a Custom force.

Parameters:

	forces	the subsystem to which this force should be added
	implementation	the object which implements the custom force. The Force::Custom takes over ownership of the implementation object, and deletes it when the Force itself is deleted.
