Enum Constant Detail

TRIGGER_ONLY_DECREASING_EVENTS

public static final FilterType TRIGGER_ONLY_DECREASING_EVENTS

Constant for triggering only decreasing events.

When this filter is used, the wrapped event handler eventOccurred method will be called only with its increasing argument set to false.

TRIGGER_ONLY_INCREASING_EVENTS

public static final FilterType TRIGGER_ONLY_INCREASING_EVENTS

Constant for triggering only increasing events.

When this filter is used, the wrapped event handler eventOccurred method will be called only with its increasing argument set to true.

Method Detail

values

public static FilterType[] 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 (FilterType c : FilterType.values())
    System.out.println(c);

Returns:

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

valueOf

public static FilterType 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

getTriggeredIncreasing

protected abstract boolean getTriggeredIncreasing()

Get the increasing status of triggered events.

Returns:

true if triggered events are increasing events

selectTransformer

protected abstract org.apache.commons.math4.legacy.ode.events.Transformer selectTransformer(org.apache.commons.math4.legacy.ode.events.Transformer previous,
                                                                                            double g,
                                                                                            boolean forward)

Get next function transformer in the specified direction.

Parameters:

previous - transformer active on the previous point with respect to integration direction (may be null if no previous point is known)

g - current value of the g function

forward - true if integration goes forward

Returns:

next transformer transformer
