APIResponse

@Target(value=METHOD)
 @Retention(value=RUNTIME)
 @Inherited
 @Repeatable(value=APIResponses.class)
public @interface APIResponse
```
The APIResponse annotation corresponds to the OpenAPI Response model object which describes a single response from an API Operation, including design-time, static links to operations based on the response.
When this annotation is applied to a JAX-RS method the response is added to the responses defined in the corresponding OpenAPI operation. If the operation already has a response with the specified responseCode the annotation on the method is ignored.
```
 @APIResponse(responseCode="200", description="Calculate load size", content=
     { @Content(mediaType="application/json", Schema=@Schema(type="integer")) } )
 @GET
 public getLuggageWeight(Flight id) {
     return getBagWeight(id) + getCargoWeight(id);
 }
 
```
When this annotation is applied to an ExceptionMapper, it allows developers to describe the API response that will be added to a generated OpenAPI operation based on a JAX-RS method that declares an Exception of the type handled by the ExceptionMapper.
```
 @Provider
 public class NotFoundExceptionMapper implements ExceptionMapper<NotFoundException> {
     @Override
     @APIResponse(responseCode = "404", description = "Not Found")
     public Response toResponse(NotFoundException t) {
         return Response.status(404)
                 .type(MediaType.TEXT_PLAIN)
                 .entity("Not found")
                 .build();
     }
 }
 
```

```
public abstract java.lang.String description
```
    A short description of the response. It is a REQUIRED property unless this is only a reference to a response instance.
    
    Returns:
    
    description of the response.
    
    Default:
    
    ""
- - responseCode
```
public abstract java.lang.String responseCode
```
    The HTTP response code, or 'default', for the supplied response. May only have 1 default entry.
    
    Returns:
    
    HTTP response code for this response instance or default
    
    Default:
    
    "default"
- - headers
```
public abstract Header[] headers
```
    An array of response headers. Allows additional information to be included with response.
    RFC7230 states header names are case insensitive. If a response header is defined with the name "Content-Type", it SHALL be ignored.
    
    Returns:
    
    array of headers for this response instance
    
    Default:
    
    {}
- - links
```
public abstract Link[] links
```
    An array of operation links that can be followed from the response.
    
    Returns:
    
    array of operation links for this response instance
    
    Default:
    
    {}
- - content
```
public abstract Content[] content
```
    An array containing descriptions of potential response payloads for different media types.
    
    Returns:
    
    content of this response instance
    
    Default:
    
    {}
- - name
```
public abstract java.lang.String name
```
    The unique name to identify this response. Only REQUIRED when the response is defined within Components. The name will be used as the key to add this response to the 'responses' map for reuse.
    
    Returns:
    
    this response's name
    
    Default:
    
    ""
- - ref
```
public abstract java.lang.String ref
```
    Reference value to a Response object.
    This property provides a reference to an object defined elsewhere. This property and all other properties are mutually exclusive. If other properties are defined in addition to the ref property then the result is undefined.
    
    Returns:
    
    reference to a response
    
    Default:
    
    ""
