Enum Constant Detail

BUNDLE

public static final ReferenceScope BUNDLE

A single service object is used for all references to the service in this bundle.

PROTOTYPE

public static final ReferenceScope PROTOTYPE

If the referenced service has prototype service scope, then each instance of the component with this reference can receive a unique instance of the service. If the referenced service does not have prototype service scope, then no service object will be received.

Method Detail

values

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

Returns:

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

valueOf

public static ReferenceScope 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

toString

public String toString()

Overrides:
