T
- the type of the field elementspublic interface FieldODEFixedStepHandler<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 FieldODEStepHandler
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.
Modifier and Type | Method | Description |
---|---|---|
void |
handleStep(FieldODEStateAndDerivative<T> state,
boolean isLast) |
Handle the last accepted step
|
default void |
init(FieldODEStateAndDerivative<T> initialState,
T finalTime) |
Initialize step handler at the start of an ODE integration.
|
default 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.
The default implementation does nothing.
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 © 2016–2018 Hipparchus.org. All rights reserved.
