Enum ApplicationState

java.lang.Object

java.lang.Enum<ApplicationState>

org.apache.cassandra.gms.ApplicationState

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ApplicationState>

public enum ApplicationState
extends java.lang.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 set of sstable versions on this node. This will usually be only the "current" sstable format (the one with which new sstables are written), but may contain more on newly upgraded nodes before `upgradesstable` has been run.

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

Method Detail

values

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

Returns:

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

valueOf

public static ApplicationState 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
