Enum Constant Detail

INCREMENT

public static final StepNormalizerMode INCREMENT
Steps are fixed increments of the start value. In other words, they are relative to the start value.

If the integration start time is t0, then the points handled by the underlying fixed step size step handler are t0 (depending on the bounds settings), t0+h, t0+2h, ...

If the integration range is an integer multiple of the step size (h), then the last point handled will be the end point of the integration (tend). If not, the last point may be the end point tend, or it may be a point belonging to the interval [tend - h ; tend], depending on the bounds settings.

MULTIPLES

public static final StepNormalizerMode MULTIPLES
Steps are multiples of a fixed value. In other words, they are relative to the first multiple of the step size that is encountered after the start value.

If the integration start time is t0, and the first multiple of the fixed step size that is encountered is t1, then the points handled by the underlying fixed step size step handler are t0 (depending on the bounds settings), t1, t1+h, t1+2h, ...

If the end point of the integration range (tend) is an integer multiple of the step size (h) added to t1, then the last point handled will be the end point of the integration (tend). If not, the last point may be the end point tend, or it may be a point belonging to the interval [tend - h ; tend], depending on the bounds settings.

Method Detail

values

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

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

valueOf

public static StepNormalizerMode 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
