Annotation Type Ref

@Target(value=FIELD)
 @Retention(value=RUNTIME)
public @interface Ref

Specifies a link injection target in a returned representation bean. May be used on fields of type String or URI. One of value() or resource() must be specified.

Optional Element Summary

Optional Elements

Modifier and Type	Optional Element and Description
Binding[]	bindings Specifies the bindings for embedded URI template parameters.
String	condition Specifies a boolean EL expression whose value determines whether a Ref is set (true) or not (false).
String	method Used in conjunction with resource() to specify a subresource locator or method.
Class<?>	resource Specifies a resource class whose @Path URI template will be used to build the injected URI.
Ref.Style	style The style of URI to inject
String	value Specifies a URI template that will be used to build the injected URI.

Element Detail

style

public abstract Ref.Style style

The style of URI to inject

Default:

com.sun.jersey.server.linking.Ref.Style.ABSOLUTE_PATH

value

public abstract String value

Specifies a URI template that will be used to build the injected URI. The template may contain both URI template parameters (e.g. {id}) and EL expressions (e.g. ${instance.id}) using the same implicit beans as Binding.value(). URI template parameter values are resolved as described in resource(). E.g. the following three alternatives are equivalent:

 @Ref("{id}")
 @Ref(value="{id}", bindings={
   @Binding(name="id" value="${instance.id}"}
 )
 @Ref("${instance.id}")
 

Default:

""

resource

public abstract Class<?> resource

Specifies a resource class whose @Path URI template will be used to build the injected URI. Embedded URI template parameter values are resolved as follows:

1. If the bindings() property contains a binding specification for the parameter then that is used
2. Otherwise an implicit binding is used that extracts the value of a bean property by the same name as the URI template from the implicit instance bean (see Binding).

E.g. assuming a resource class SomeResource with the following @Path("{id}") annotation, the following two alternatives are therefore equivalent:

 @Ref(resource=SomeResource.class)
 @Ref(resource=SomeResource.class, bindings={
   @Binding(name="id" value="${instance.id}"}
 )
 

Default:

java.lang.Class.class

method

public abstract String method

Used in conjunction with resource() to specify a subresource locator or method. The value is the name of the method. The value of the method's @Path annotation will be appended to the value of the class-level @Path annotation separated by '/' if necessary.

Default:

""

bindings

public abstract Binding[] bindings

Specifies the bindings for embedded URI template parameters.

Binding

Default:

{}

condition

public abstract String condition

Specifies a boolean EL expression whose value determines whether a Ref is set (true) or not (false). Omission of a condition will always insert a ref.

Default:

""
