Enum LifecycleState

java.lang.Object

java.lang.Enum<LifecycleState>

com.atlassian.johnson.spring.lifecycle.LifecycleState

All Implemented Interfaces:

Serializable, Comparable<LifecycleState>

public enum LifecycleState
extends Enum<LifecycleState>

Enumerates certain key lifecycle states. An application may have many more fine-grained states than this limited set. These states are enumerated here specifically because they are relevant to Johnson's components.

Since:

3.0

Enum Constant Detail

CREATED

public static final LifecycleState CREATED

The application has been created but has not attempted to start. This is a placeholder state used when no explicit state has been set.

FAILED

public static final LifecycleState FAILED

An attempt to start the application failed. Application components like filters and servlets will likely never be available.

STARTED

public static final LifecycleState STARTED

The application has started successfully. All expected components like filters and servlets should be available.

STARTING

public static final LifecycleState STARTING

The application is starting. Components may progressively become available during this state, but delegating placeholders (like filter proxies) should not attempt to bind to them yet.

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
