Enum Constant Detail

INITIAL

public static final Partition.State INITIAL

The partition has been defined, but not enabled

ACTIVE

public static final Partition.State ACTIVE

The partition is active

UPDATING

public static final Partition.State UPDATING

The partition definition is being updated. Entered when partition membership (i.e. the objects associated with the partition) is being updated to split or merge partitions.

MIGRATING

public static final Partition.State MIGRATING

The partition owner is being updated. Each object in the partition is sent to the new owner and the location definition of all instances are updated.

REPLICATING

public static final Partition.State REPLICATING

The partition replicas are being updated. Each object in the partition is sent to the new replica list.

UNAVAILABLE

public static final Partition.State UNAVAILABLE

The partition is not active because all associated nodes have failed, the node was taken off-line because it is in a non-quorum state, or the node was restarted.

Method Detail

values

public static Partition.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 (Partition.State c : Partition.State.values())
    System.out.println(c);

Returns:

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

valueOf

public static Partition.State valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
