UP

public static final ClusterStatusReport.NodeStatus UP

Node is reachable.

DB_SYNCING

public static final ClusterStatusReport.NodeStatus DB_SYNCING

Node is reachable but does not have complete data redundancy.

DOWN

public static final ClusterStatusReport.NodeStatus DOWN

Node is not reachable.

NA

public static final ClusterStatusReport.NodeStatus NA

Whenever the state of a node cannot be determined. If a client looses connection to all nodes it is wrong to report them DOWN, nodes might be up and clients are unable to connect.

Method Detail

values

public static ClusterStatusReport.NodeStatus[] 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 (ClusterStatusReport.NodeStatus c : ClusterStatusReport.NodeStatus.values())
    System.out.println(c);

Returns:

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

valueOf

public static ClusterStatusReport.NodeStatus 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:
