Interface SymmetricInteractionRule

All Superinterfaces:

InteractionRule

All Known Implementing Classes:

ElasticBallsInteractionRule

public interface SymmetricInteractionRule
extends InteractionRule

True interaction between two objects, according Newton's 3rd law. If a class implements this interface, then there is a guarantee that InteractionRule.isApplicable(Item, Item) method returns the same result not depending on the order of its arguments, and if calculateForce(resultXYZ, item1, item2, time) returns some force F=(F_x,F_y,F_z) (in first 3 elements of resultXYZ array), then the symmetric call calculateForce(resultXYZ, item2, item1, time) returns the force −F=(−F_x,−F_y,−F_z).
