org.eclipse.gemini.blueprint.extender.internal.dependencies.startup.ContextState

All Implemented Interfaces:

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

public enum ContextState
extends java.lang.Enum<ContextState>

State of an application context while being processed by DependencyWaiterApplicationContextExecutor. This enumeration holds the state of an application context at a certain time, beyond the official states such as STARTED/STOPPED.

Enum Constant Summary

Enum Constants

Enum Constant and Description
DEPENDENCIES_RESOLVED Application context has been started and the OSGi dependencies have been resolved.
INITIALIZED Application context has been initialized but not started (i.e.
INTERRUPTED Application context has been interrupted.
RESOLVING_DEPENDENCIES Application context has been started but the OSGi service dependencies haven't been yet resolved.
STARTED Application context has been fully initialized.
STOPPED Application context has been stopped.

Method Summary

Modifier and Type	Method and Description
boolean	isDown() Indicates whether the state is 'down' or not - that is a context which has been either closed or stopped.
boolean	isResolved()
boolean	isUnresolved() Indicates whether the state is unresolved or not.
static ContextState	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static ContextState[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

INITIALIZED

public static final ContextState INITIALIZED

Application context has been initialized but not started (i.e. refresh hasn't been called).

RESOLVING_DEPENDENCIES

public static final ContextState RESOLVING_DEPENDENCIES

Application context has been started but the OSGi service dependencies haven't been yet resolved.

DEPENDENCIES_RESOLVED

public static final ContextState DEPENDENCIES_RESOLVED

Application context has been started and the OSGi dependencies have been resolved. However the context is not fully initialized (i.e. refresh hasn't been completed).

STARTED

public static final ContextState STARTED

Application context has been fully initialized. The OSGi dependencies have been resolved and refresh has fully completed.

INTERRUPTED

public static final ContextState INTERRUPTED

Application context has been interrupted. This state occurs if the context is being closed before being fully started.

STOPPED

public static final ContextState STOPPED

Application context has been stopped. This can occur even only if the context has been fully started for example; otherwise INTERRUPTED state should be used.

Method Detail

values

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

Returns:

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

valueOf

public static ContextState 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

isDown

public boolean isDown()

Indicates whether the state is 'down' or not - that is a context which has been either closed or stopped.

Returns:

true if the context has been interrupted or stopped, false otherwise.

isUnresolved

public boolean isUnresolved()

Indicates whether the state is unresolved or not. An unresolved state means a state which is active (started) in RESOLVING_DEPENDENCIES state.

Returns:

isResolved

public boolean isResolved()
