Constructor Detail

TimeIntervalDetector

public TimeIntervalDetector(EventHandler handler,
                            TimeInterval timeInterval)

Constructor with default detection settings.

Parameters:

handler - event handler

timeInterval - time interval

TimeIntervalDetector

public TimeIntervalDetector(EventDetectionSettings detectionSettings,
                            EventHandler handler,
                            TimeInterval timeInterval)

Constructor.

Parameters:

detectionSettings - event detection settings

handler - event handler

timeInterval - time interval

Method Detail

getTimeInterval

public TimeInterval getTimeInterval()

Getter for the time interval.

Returns:

interval

create

protected TimeIntervalDetector create(EventDetectionSettings detectionSettings,
                                      EventHandler newHandler)

Description copied from class: AbstractDetector

Build a new instance.

Specified by:

create in class AbstractDetector<TimeIntervalDetector>

Parameters:

detectionSettings - detection settings

newHandler - event handler to call at event occurrences

Returns:

a new instance of the appropriate sub-type

dependsOnTimeOnly

public boolean dependsOnTimeOnly()

Method returning true if and only if the detection function g does not depend on dependent variables, just the independent one i.e. time. This information is used for performance in propagation.

Returns:

flag

g

public double g(SpacecraftState s)

Description copied from interface: EventDetector

Compute the value of the switching function. This function must be continuous (at least in its roots neighborhood), as the integrator will need to find its roots to locate the events.

Parameters:

s - the current state information: date, kinematics, attitude

Returns:

value of the switching function
