public static enum Sequence.State
The possible internal states a Sequence
can have.
Sequence.state()
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. |

sequence will have this internal state if it has restarted its
sequence of values.
public static final Sequence.State START
Sequence.next()
, nor
Sequence.reset()
has been invoked yet.
However, a current
value
can still be obtained as sequences never return
null values.

- the name of the enum constant to be returned.
IllegalArgumentException
- if this enum type has no constant
with the specified name
NullPointerException
- if the argument is nullpublic static Sequence.State[] values()
