      extended by org.springframework.beans.factory.annotation.Autowire
All Implemented Interfaces:
Serializable, Comparable<Autowire>

public enum Autowire
extends Enum<Autowire>

Enumeration determining autowiring status: that is, whether a bean should have its dependencies automatically injected by the Spring container using setter injection. This is a core concept in Spring DI.

Available for use in annotation-based configurations, such as for the AspectJ AnnotationBeanConfigurer aspect.

Enum Constant Detail

NO

public static final Autowire NO
Constant that indicates no autowiring at all.


BY_NAME

public static final Autowire BY_NAME
Constant that indicates autowiring bean properties by name.


BY_TYPE

public static final Autowire BY_TYPE
Constant that indicates autowiring bean properties by type.

Method Detail

values

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

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

valueOf

public static Autowire 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

value

public int value()

isAutowire

public boolean isAutowire()
Return whether this represents an actual autowiring value.

Returns:
whether actual autowiring was specified (either BY_NAME or BY_TYPE)
