Enum Constant Detail- 
INACTIVEpublic static final ClusterState INACTIVE Cluster deactivated. Cache operations aren't allowed.NOTE: Deactivation clears in-memory caches (without persistence) including the system caches. 
 - 
ACTIVEpublic static final ClusterState ACTIVE Cluster activated. All cache operations are allowed.
 - 
ACTIVE_READ_ONLYpublic static final ClusterState ACTIVE_READ_ONLY Cluster activated. Cache read operation allowed, Cache data change operation aren't allowed.

Method Detail- 
valuespublic 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
 
 - 
valueOfpublic 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 name
- NullPointerException- if the argument is null
 
 - 
activepublic boolean active() - Returns:
- Trueif cluster activated in this state and- falseotherwise.
 
 - 
fromOrdinal@Nullable public static @Nullable ClusterState fromOrdinal(int ord) Efficiently gets enumerated value from its ordinal.- Parameters:
- ord- Ordinal value.
- Returns:
- Enumerated value or nullif ordinal out of range.
