T - the type of the field elementspublic interface FieldFixedStepHandler<T extends RealFieldElement<T>>
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 FieldStepNormalizer that itself
is used as the general FieldStepHandler by the integrator. The
FieldStepNormalizer object is called according to the integrator
internal algorithms and it calls objects implementing this
interface as necessary at fixed time steps.
FieldStepHandler,

FieldStepInterpolator| Modifier and Type | Method and Description |
|---|---|
void |
handleStep(FieldODEStateAndDerivative<T> state,
boolean isLast)
Handle the last accepted step
|
void |
init(FieldODEStateAndDerivative<T> initialState,
T finalTime)
Initialize step handler at the start of an ODE integration.
|
void init(FieldODEStateAndDerivative<T> initialState, T finalTime)
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.
initialState - initial time, state vector and derivativefinalTime - target time for the integrationvoid handleStep(FieldODEStateAndDerivative<T> state, boolean isLast)
state - current value of the independent time variable,
state vector and derivative
For efficiency purposes, the FieldStepNormalizer 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 oneCopyright © 2003–2016 The Apache Software Foundation. All rights reserved.
