@Retention(RUNTIME)
@Target({METHOD,PARAMETER,CONSTRUCTOR,FIELD})
public @interface RequestObject

Specifies which element should be converted by RequestConverterFunction.

A RequestObject can be implicitly applied when:

A parameter is neither annotated nor automatically injected type in an annotated method.
A RequestConverter annotation is specified on a parameter in an annotated method or a setter of a bean.
A RequestConverter annotation is specified on a field of a bean.
A RequestConverter annotation is specified on a method or constructor which has only one parameter.

The following example shows when to apply a RequestObject implicitly.


 > @RequestConverter(ErinConverter.class)
 > @RequestConverter(FrankConverter.class)
 > public class CompositeBean {
 >     private final Alice a;
 >
 >     @RequestConverter(BobConverter.class)      // @RequestObject would be applied implicitly.
 >     private Bob b;
 >
 >     private Charlie c;
 >     private David d;
 >     private Erin e;
 >
 >     @RequestObject
 >     private Frank f;                           // Would be converted by the class-level converter.
 >
 >     private String g;                          // No conversion would be performed. 'null' would be set.
 >
 >     @RequestConverter(AliceConverter.class)    // @RequestObject would be applied implicitly.
 >     public CompositeBean(Alice a) { ... }
 >
 >     @RequestConverter(CharlieConverter.class)  // @RequestObject would be applied implicitly.
 >     public void setCharlie(Charlie c) { ... }
 >
 >     // @RequestObject would be applied implicitly.
 >     public void setDavidAndErin(@RequestConverter(DavidConverter.class) David d, Erin e) { ... }
 > }
