Class DummyStepInterpolator

java.lang.Object
org.apache.commons.math.ode.sampling.AbstractStepInterpolator
org.apache.commons.math.ode.sampling.DummyStepInterpolator
All Implemented Interfaces:
Externalizable, Serializable, StepInterpolator

public class DummyStepInterpolator extends AbstractStepInterpolator
This class is a step interpolator that does nothing.

This class is used when the "step handler" set up by the user does not need step interpolation. It does not recompute the state when setInterpolatedTime is called. This implies the interpolated state is always the state at the end of the current step.

      public DummyStepInterpolator()
      Simple constructor. This constructor builds an instance that is not usable yet, the AbstractStepInterpolator.reinitialize protected method should be called before using the instance in order to initialize the internal arrays. This constructor is used only in order to delay the initialization in some cases. As an example, the EmbeddedRungeKuttaIntegrator uses the prototyping design pattern to create the step interpolators by cloning an uninitialized model and latter initializing the copy.
    • DummyStepInterpolator

      public DummyStepInterpolator(double[] y, double[] yDot, boolean forward)
      Simple constructor.
      Parameters:
      y - reference to the integrator array holding the state at the end of the step
      yDot - reference to the integrator array holding the state derivative at some arbitrary point within the step
      forward - integration direction indicator
    • DummyStepInterpolator

      public DummyStepInterpolator(DummyStepInterpolator interpolator)
      Copy constructor.
      Parameters:
      interpolator - interpolator to copy from. The copy is a deep copy: its arrays are separated from the original arrays of the instance
