Package org.apache.cassandra.gms

Enum Class ApplicationState

java.lang.Object

java.lang.Enum<ApplicationState>

org.apache.cassandra.gms.ApplicationState

All Implemented Interfaces:

Serializable, Comparable<ApplicationState>, Constable

public enum ApplicationState
extends Enum<ApplicationState>

The various "states" exchanged through Gossip.

Important Note: Gossip uses the ordinal of this enum in the messages it exchanges, so values in that enum should not be re-ordered or removed. The end of this enum should also always include some "padding" so that if newer versions add new states, old nodes that don't know about those new states don't "break" deserializing those states.

SSTABLE_VERSIONS

public static final ApplicationState SSTABLE_VERSIONS

The value (a set of sstable Version) is serialized as a comma-separated list.

Method Details

values

public static ApplicationState[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static ApplicationState valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:
