Base class for composite simulations.

Concrete subclasses must implement the currentSimulation getter, the currentIntervalOffset getter, and the step function to select the appropriate simulation at a given time interval. This class implements the x, dx, and isDone functions by calling the step method if necessary and then deferring to the currentSimulation's methods with a time offset by currentIntervalOffset.

The tolerance of this simulation is pushed to the simulations that are used by this group as they become active. This mean simulations should not be shared among different groups that are active at the same time.

Properties

currentIntervalOffset → double

The time offset applied to the currently active simulation when deferring x, dx, and isDone to it.

Methods

dx(double time) → double

The velocity of the object in the simulation at the given time.

isDone(double time) → bool

Whether the simulation is "done" at the given time.

step(double time) → bool

Called when a significant change in the interval is detected. Subclasses must decide if the current simulation must be switched (or updated).

x(double time) → double

The position of the object in the simulation at the given time.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
toString() → String

Returns a string representation of this object.
