Enum Constant Detail

STOP

public static final EventHandler.Action STOP

Stop indicator.

This value should be used as the return value of the eventOccurred method when the integration should be stopped after the event ending the current step.

RESET_STATE

public static final EventHandler.Action RESET_STATE

Reset state indicator.

This value should be used as the return value of the eventOccurred method when the integration should go on after the event ending the current step, with a new state vector (which will be retrieved thanks to the resetState method).

RESET_DERIVATIVES

public static final EventHandler.Action RESET_DERIVATIVES

Reset derivatives indicator.

This value should be used as the return value of the eventOccurred method when the integration should go on after the event ending the current step, with a new derivatives vector (which will be retrieved thanks to the FirstOrderDifferentialEquations.computeDerivatives(double, double[], double[]) method).

CONTINUE

public static final EventHandler.Action CONTINUE

Continue indicator.

This value should be used as the return value of the eventOccurred method when the integration should go on after the event ending the current step.

Method Detail

values

public static EventHandler.Action[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (EventHandler.Action c : EventHandler.Action.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static EventHandler.Action valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
