Interface FixedStepHandler


public interface FixedStepHandler

This interface represents a handler that should be called after each successful fixed step.

This interface should be implemented by anyone who is interested in getting the solution of an ordinary differential equation at fixed time steps. Objects implementing this interface should be wrapped within an instance of StepNormalizer that itself is used as the general StepHandler by the integrator. The StepNormalizer object is called according to the integrator internal algorithms and it calls objects implementing this interface as necessary at fixed time steps.

Method Summary
 void handleStep(double t, double[] y, boolean isLast)
          Handle the last accepted step
 

Method Detail

handleStep

void handleStep(double t,
                double[] y,
                boolean isLast)
Handle the last accepted step

Parameters:
t - time of the current step
y - state vector at t. For efficiency purposes, the StepNormalizer class reuse the same array on each call, so if the instance wants to keep it across all calls (for example to provide at the end of the integration a complete array of all steps), it should build a local copy store this copy.
isLast - true if the step is the last one
