Enum Constant Summary

NORMAL
Internal state of any sequence unless START, RESET, or RESTART applies to it.

RESET
Internal state explicitly set using Sequence.reset().

RESTART
A bounded and consistent sequence will have this internal state if it has restarted its sequence of values.

START
Initial internal state: neither Sequence.next(), nor Sequence.reset() has been invoked yet.

Method Summary

static Sequence.State	valueOf(String name) Returns the enum constant of this type with the specified name.
static Sequence.State[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

NORMAL

public static final Sequence.State NORMAL

Internal state of any sequence unless START, RESET, or RESTART applies to it.

RESET

public static final Sequence.State RESET

Internal state explicitly set using Sequence.reset().

RESTART

public static final Sequence.State RESTART

A bounded and consistent sequence will have this internal state if it has restarted its sequence of values.

START

public static final Sequence.State START

Initial internal state: neither Sequence.next(), nor Sequence.reset() has been invoked yet.

However, a current value can still be obtained as sequences never return null values.

Method Detail

valueOf

public static Sequence.State 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

values

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

Returns:

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