Method Summary

Modifier and Type	Method	Description
boolean	dependsOnTimeOnly()	Method returning true if and only if the event function does not depend on dependent variables, just the independent one i.e. time.
<T extends CalculusFieldElement<T>> T	value(FieldSpacecraftState<T> fieldState)	Evaluate Field function.
double	value(SpacecraftState state)	Evaluate function.

Constructor Detail

SingleDateEventFunction

public SingleDateEventFunction(AbsoluteDate date)

Constructor.

Parameters:

date - event date

Method Detail

value

public double value(SpacecraftState state)

Description copied from interface: EventFunction

Evaluate function.

Specified by:

value in interface EventFunction

Parameters:

state - spacecraft state

Returns:

value

value

public <T extends CalculusFieldElement<T>> T value(FieldSpacecraftState<T> fieldState)

Description copied from interface: EventFunction

Evaluate Field function. By default, calls the non-Field version. This is suitable for detection but not be for applications like automatic differentiation, where a proper implementation should be used instead.

Specified by:

value in interface EventFunction

Type Parameters:

T - field type

Parameters:

fieldState - spacecraft state

Returns:

value

dependsOnTimeOnly

public boolean dependsOnTimeOnly()

Description copied from interface: EventFunction

Method returning true if and only if the event function 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.

Specified by:

dependsOnTimeOnly in interface EventFunction

Returns:

flag
