values
public static ClusterState[] 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 (ClusterState c : ClusterState.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static ClusterState 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 nameNullPointerException
- if the argument is null
-
active
public boolean active()
- Returns:
True
if cluster activated in this state andfalse
otherwise.
-
fromOrdinal
@Nullable public static @Nullable ClusterState fromOrdinal(int ord)
Efficiently gets enumerated value from its ordinal.- Parameters:
ord
- Ordinal value.- Returns:
- Enumerated value or
null
if ordinal out of range.
