Enum Constant Detail

UNAVAILABLE

public static final OptionalDependency.DependencyState UNAVAILABLE

The dependency is unavailable; means the last notification received by this OptionalDependency (as a dependent of the real dependency) is #dependencyUnavailable.

AVAILABLE

public static final OptionalDependency.DependencyState AVAILABLE

The dependency is available, but is not up. This is the initial state of the dependency. Also, if any notification has been made by the dependency, this will be the dependency state if the last notification received is #dependencyInstalled, #dependencyDown, or #dependencyRetrying.

UP

public static final OptionalDependency.DependencyState UP

The dependency is up; means the last notification received by this OptionalDependency (as a dependent of the real dependency) is #dependencyUp.

Method Detail

values

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

Returns:

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

valueOf

public static OptionalDependency.DependencyState 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
