Class Response

java.lang.Object
javax.ws.rs.core.Response
public abstract class Response extends Object
Defines the contract between a returned instance and the runtime when an application needs to provide metadata to the runtime. An application class can extend this class directly or can use one of the static methods to create an instance using a ResponseBuilder. Several methods have parameters of type URI, UriBuilder provides convenient methods to create such values as does

  • Constructor Details

    • Response

      protected Response()
      Protected constructor, use one of the static methods to obtain a Response.ResponseBuilder instance and obtain a Response from that.

  • Method Details

    • getEntity

      public abstract Object getEntity()
      Return the response entity. The response will be serialized using a MessageBodyWriter for either the class of the entity or, in the case of GenericEntity, the value of GenericEntity.getRawType().
      Returns:
      an object instance or null if there is no entity

    • getStatus

      public abstract int getStatus()
      Get the status code associated with the response.
      Returns:
      the response status code or -1 if the status was not set.

    • getMetadata

      public abstract MultivaluedMap<String,Object> getMetadata()
      Get metadata associated with the response as a map. The returned map may be subsequently modified by the JAX-RS runtime. Values will be serialized using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the class of the value or using the values toString method if a header delegate is not available.
      Returns:
      response metadata as a map

    • fromResponse

      public static Response.ResponseBuilder fromResponse(Response response)
      Create a new ResponseBuilder by performing a shallow copy of an existing Response. The returned builder has its own metadata map but entries are simply references to the keys and values contained in the supplied Response metadata map.

      response - a Response from which the status code, entity and metadata will be copied
      Returns:
      a new ReponseBuilder

      status - the response status
      Returns:
      a new ResponseBuilder
      Throws:
      IllegalArgumentException - if status is null

      Create a new ResponseBuilder with the supplied status.
      Parameters:
      status - the response status
      Returns:
      a new ResponseBuilder
      Throws:
      IllegalArgumentException - if status is null

    • status

      public static Response.ResponseBuilder status(int status)
      Create a new ResponseBuilder with the supplied status.
      Parameters:
      status - the response status

      a new ResponseBuilder
      Throws:
      IllegalArgumentException - if status is less than 100 or greater than 599.

    • ok

      public static Response.ResponseBuilder ok()
      Create a new ResponseBuilder with an OK status.
      Returns:
      a new ResponseBuilder

    • ok

      public static Response.ResponseBuilder ok(Object entity)
      Create a new ResponseBuilder that contains a representation. It is the callers responsibility to wrap the actual entity with GenericEntity if preservation of its generic type is required.
      Parameters:
      entity - the representation entity data
      Returns:
      a new ResponseBuilder

    • ok

      public static Response.ResponseBuilder ok(Object entity, MediaType type)
      Create a new ResponseBuilder that contains a representation. It is the callers responsibility to wrap the actual entity with GenericEntity if preservation of its generic type is required.
      Parameters:
      entity - the representation entity data
      type - the media type of the entity
      Returns:
      a new ResponseBuilder

    • ok

      public static Response.ResponseBuilder ok(Object entity, String type)
      Create a new ResponseBuilder that contains a representation. It is the callers responsibility to wrap the actual entity with GenericEntity if preservation of its generic type is required.
      Parameters:
      entity - the representation entity data
      type - the media type of the entity
      Returns:
      a new ResponseBuilder

    • ok

      public static Response.ResponseBuilder ok(Object entity, Variant variant)
      Create a new ResponseBuilder that contains a representation. It is the callers responsibility to wrap the actual entity with GenericEntity if preservation of its generic type is required.
