Constructor Detail

FieldTimeIntervalDetector

public FieldTimeIntervalDetector(Field<T> field,
                                 TimeInterval timeInterval)

Constructor with default detection settings and handler.

Parameters:

field - field

timeInterval - time interval

FieldTimeIntervalDetector

public FieldTimeIntervalDetector(FieldEventDetectionSettings<T> detectionSettings,
                                 FieldEventHandler<T> 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 FieldTimeIntervalDetector<T> create(FieldEventDetectionSettings<T> detectionSettings,
                                              FieldEventHandler<T> newHandler)

Description copied from class: FieldAbstractDetector

Build a new instance.

Specified by:

create in class FieldAbstractDetector<FieldTimeIntervalDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>

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 and derivatives correction with switches in the dynamics.

Returns:

flag

g

public T g(FieldSpacecraftState<T> s)

Description copied from interface: FieldEventDetector

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
