Enum Constants

Enum Constant and Description
BUNDLE When the component is registered as a service, it must be registered as a bundle scope service and an instance of the component must be created for each bundle using the service.
PROTOTYPE When the component is registered as a service, it must be registered as a prototype scope service and an instance of the component must be created for each distinct request for the service.
SINGLETON When the component is registered as a service, it must be registered as a singleton: only a single instance of the component must be used for all service consumers.

Enum Constant Detail

SINGLETON

public static final Component.ServiceScope SINGLETON

When the component is registered as a service, it must be registered as a singleton: only a single instance of the component must be used for all service consumers. SINGLETON scope is the default scope.

BUNDLE

public static final Component.ServiceScope BUNDLE

When the component is registered as a service, it must be registered as a bundle scope service and an instance of the component must be created for each bundle using the service.

PROTOTYPE

public static final Component.ServiceScope PROTOTYPE

When the component is registered as a service, it must be registered as a prototype scope service and an instance of the component must be created for each distinct request for the service.

Method Detail

values

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

Returns:

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

valueOf

public static Component.ServiceScope 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
