Enum Autowire

java.lang.Object
  java.lang.Enum<Autowire>
      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.

Since:

2.0

Enum Constant Detail

INHERITED

public static final Autowire INHERITED

Constant that indicates that autowiring information was not specified. In some cases it may be necessary to specify autowiring status, but merely confirm that this should be inherited from an enclosing container definition scope.

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 final Autowire[] values()

Returns an array containing the constants of this enum type, in the order they're 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're 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

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)
