java.lang.Object

java.lang.Enum<Cardinality>

aQute.bnd.annotation.Cardinality

All Implemented Interfaces:

Serializable, Comparable<Cardinality>

public enum Cardinality
extends Enum<Cardinality>

For use in the creation of custom bundle annotations wishing to control the cardinality of generated requirements.

The Enum.name will automatically be converted to lower case during macro processing.

Enum Constant Detail

SINGLE

public static final Cardinality SINGLE

Indicates if the requirement can only be wired a single time.

MULTIPLE

public static final Cardinality MULTIPLE

Indicates if the requirement can be wired multiple times.

DEFAULT

public static final Cardinality DEFAULT

Default element value for annotation. This is used to distinguish the default value for an element and should not otherwise be used.

Method Detail

values

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

Returns:

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

valueOf

public static Cardinality 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:

toString in class Enum<Cardinality>
