Annotation Type NullOrNotNullAll

@Target(value=TYPE)
@Retention(value=RUNTIME)
@Documented
@Inherited
public @interface NullOrNotNullAll

Use this annotation to specify that methods and/or fields must be all NULL or NOT NULL. For instance: @NullOrNotNullAll(values="#{me.anotherProperty}","#{me.child.name}") means that both field/method's value must be non-null or both must null. It is recommended to use the customMessage attribute to define a useful message to present to your users.

Class level annotation!

Note: As this is a classlevel annotation the message is global by DEFAULT.

Optional Element Summary

java.lang.String[]	applyToGroups Specify for which groups this annotation must be applied.
java.lang.String	customCode Optional custom code (property from a properties file).
boolean	globalMessage If this annotation's message must be added as global message instead of real validation path.
java.lang.String[]	values Values is required.

applyToGroups

public abstract java.lang.String[] applyToGroups

Specify for which groups this annotation must be applied. By default if you annotate without this variable, the annotation is applied for any group on that method (which is what you usually want). However by specifying the exact groups you can turn on/off a validation on a method depending on the group you validate.

Defaults to JvGroup.GROUP_APPLY_ALL

Default:

"_all_"

customCode

public abstract java.lang.String customCode

Optional custom code (property from a properties file). If set, this one is used instead of the default one specified in MessageCodes.

This way you can override the default message if needed.

Default:

""

globalMessage

public abstract boolean globalMessage

If this annotation's message must be added as global message instead of real validation path. Defaults to true as this is a classlevel annotation.

Default:

true

values

public abstract java.lang.String[] values

Values is required. Set each entry to an expression that resolves to a method/field value. For example: {"#{me.anotherMethod}"}, where me refers to the object (class) itself (remember this is a class annotation).

You are recommended to specify a custom code message (for the sake of your users).

Default:

{}
