Simple constructor.

Method Details

add

public void add(FieldOrekitStepHandler<T> handler)

Add a handler for variable size step.

If propagation is ongoing (i.e. global init already called and global finish not called yet), then the local FieldOrekitStepHandler.init method of the added handler will be called with the last known state, so the handler starts properly.

Parameters:

handler - step handler to add

add

public void add(T h,
 FieldOrekitFixedStepHandler<T> handler)

Add a handler for fixed size step.

If propagation is ongoing (i.e. global init already called and global finish not called yet), then the local FieldOrekitStepHandler.init method of the added handler will be called with the last known state, so the handler starts properly.

Parameters:

h - fixed stepsize (s)

handler - handler called at the end of each finalized step

Since:

11.0

getHandlers

public List<FieldOrekitStepHandler<T>> getHandlers()

Get an unmodifiable view of all handlers.

Note that if fixed step handlers have been add(CalculusFieldElement, FieldOrekitFixedStepHandler), then they will show up wrapped within step normalizers.

Returns:

an unmodifiable view of all handlers

Since:

11.0

remove

public void remove(FieldOrekitStepHandler<T> handler)

Remove a handler.

If propagation is ongoing (i.e. global init already called and global finish not called yet), then the local FieldOrekitStepHandler.finish method of the removed handler will be called with the last known state, so the handler stops properly.

Parameters:

handler - step handler to remove

Since:

11.0

remove

public void remove(FieldOrekitFixedStepHandler<T> handler)

Remove a handler.

If propagation is ongoing (i.e. global init already called and global finish not called yet), then the local FieldOrekitFixedStepHandler.finish method of the removed handler will be called with the last known state, so the handler stops properly.

Parameters:

handler - step handler to remove

Since:

11.0

clear

public void clear()

Remove all handlers managed by this multiplexer.

If propagation is ongoing (i.e. global init already called and global finish not called yet), then the local FieldOrekitStepHandler.finish and FieldOrekitFixedStepHandler.finish methods of the removed handlers will be called with the last known state, so the handlers stop properly.

Since:

11.0

init

public void init(FieldSpacecraftState<T> s0,
 FieldAbsoluteDate<T> t)

Initialize step handler at the start of a propagation.

This method is called once at the start of the propagation. It may be used by the step handler to initialize some internal data if needed.

Specified by:

init in interface FieldOrekitStepHandler<T extends CalculusFieldElement<T>>

Parameters:

s0 - initial state

t - target time for the integration

handleStep

public void handleStep(FieldOrekitStepInterpolator<T> interpolator)

Handle the current step.

Specified by:

handleStep in interface FieldOrekitStepHandler<T extends CalculusFieldElement<T>>

Parameters:

interpolator - interpolator set up for the current step

finish

public void finish(FieldSpacecraftState<T> finalState)

Finalize propagation.

Specified by:

finish in interface FieldOrekitStepHandler<T extends CalculusFieldElement<T>>

Parameters:

finalState - state at propagation end
