Enum LifecycleState

java.lang.Object

java.lang.Enum<LifecycleState>

com.couchbase.client.dcp.core.state.LifecycleState

All Implemented Interfaces:

Serializable, Comparable<LifecycleState>

public enum LifecycleState
extends Enum<LifecycleState>

**Represents common lifecycle states of components.**

The LifecycleStates are usually combined with the AbstractStateMachine to build up a state-machine like, observable component that can be subscribed from external components.

Method Detail

values

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

Returns:

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

valueOf

public static LifecycleState 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
