Enum Constant Detail

NEVER

public static final CronExpressionQuantizer.Randomize NEVER

Never randomize the seconds field. If the supplied value does not meet the requirement (a simple integer from 0 to 59), then force it to 0.

AS_NEEDED

public static final CronExpressionQuantizer.Randomize AS_NEEDED

Randomize the seconds field if quantization is needed; otherwise, leave it alone. If the supplied value does not meet the requirement (a simple integer from 0 to 59), then force it to a randomized value; otherwise, leave it alone.

ALWAYS

public static final CronExpressionQuantizer.Randomize ALWAYS

Replace the seconds fields with a randomized value in all cases. The replacement is performed regardless of whether or not the value was already in the permitted format.

Method Detail

values

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

Returns:

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

valueOf

public static CronExpressionQuantizer.Randomize 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
