Interface FixedStepHandler
- All Superinterfaces:
ODEFixedStepHandler
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 Details
-
init
Deprecated.Initialize step handler at the start of an ODE integration.This method is called once at the start of the integration. It may be used by the step handler to initialize some internal data if needed.
The default implementation does nothing.

init
void init(double t0, double[] y0, double t) Deprecated.Initialize step handler at the start of an ODE integration.This method is called once at the start of the integration. It may be used by the step handler to initialize some internal data if needed.
- Parameters:
t0
- start value of the independent time variabley0
- array containing the start value of the state vectort
- target time for the integration
-
handleStep
void handleStep(double t, double[] y, double[] yDot, boolean isLast) Deprecated.Handle the last accepted step- Parameters:
t
- time of the current stepy
- state vector at t. For efficiency purposes, theStepNormalizer
class reuses 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.yDot
- derivatives of the state vector state vector at t. For efficiency purposes, theStepNormalizer
class reuses 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
