                            Predicate<EstimatedMeasurementBase<T>> filter)

Simple constructor.

Parameters:

builder - builder for individual measurements

selector - selector for dates

filter - predicate for a posteriori filtering of generated measurements (measurements are accepted if the predicates evaluates to true)

Method Detail

init

public void init(AbsoluteDate start,
                 AbsoluteDate end)

Initialize scheduler at the start of a measurements generation.

This method is called once at the start of the measurements generation. It may be used by the scheduler to initialize some internal data if needed, typically initializing builders.

This implementation initialize the measurement builder.

Specified by:

init in interface Scheduler<T extends ObservedMeasurement<T>>

Parameters:

start - start of the measurements time span

end - end of the measurements time span

getBuilder

public MeasurementBuilder<T> getBuilder()

Get the builder associated with this scheduler.

Specified by:

getBuilder in interface Scheduler<T extends ObservedMeasurement<T>>

Returns:

builder associated with this scheduler

getSelector

public DatesSelector getSelector()

Get the dates selector.

Returns:

dates selector

generate

public SortedSet<EstimatedMeasurementBase<T>> generate(Map<ObservableSatellite,OrekitStepInterpolator> interpolators)

Generate a sequence of measurements.

Specified by:

generate in interface Scheduler<T extends ObservedMeasurement<T>>

Parameters:

interpolators - interpolators for spacecraft states

Returns:

generated measurements

measurementIsFeasible

protected abstract boolean measurementIsFeasible(AbsoluteDate date)

Check if a measurement is feasible at some date.

Parameters:

date - date to check

Returns:

true if measurement if feasible
