javax.xml.bind.annotation

## Annotation Type XmlAnyAttribute

-     @Retention(value=RUNTIME)
       @Target(value={FIELD,METHOD})
      public @interface XmlAnyAttribute

  Maps a JavaBean property to a map of wildcard attributes.

  Usage

  The `@XmlAnyAttribute` annotation can be used with the following program elements:

  - JavaBean property
  - non static, non transient field

  See "Package Specification" in javax.xml.bind.package javadoc for additional common information.

  The usage is subject to the following constraints:
  - At most one field or property in a class can be annotated with `@XmlAnyAttribute`.
  - The type of the property or the field must `java.util.Map`

  While processing attributes to be unmarshalled into a value class, each attribute that is not statically associated with another JavaBean property, via `XmlAttribute`, is entered into the wildcard attribute map represented by `Map`<`QName`,`Object`>. The attribute QName is the map's key. The key's value is the String value of the attribute.

  Since:
    JAXB2.0
