    • CreateRequestBuilder

      public CreateRequestBuilder(@Nonnull String servicePath, @Nonnull EntityT entity, @Nonnull String entityCollection)
      Instantiates a CreateRequestBuilder.
      Parameters:
      servicePath - The service path to direct the requests to.
      entity - The entity to create.
      entityCollection - The entity collection

  • Method Details

    • getEntityClass

      @Nonnull protected Class<EntityT> getEntityClass()
      Returns a class object of the type this request builder works with.
      Returns:
      A class object of the handled type.

    • execute

      @Nonnull public ModificationResponse<EntityT> execute(@Nonnull Destination destination)
      Execute the OData create request for the provided entity. Execute the OData request.
      Specified by:
      execute in interface RequestBuilderExecutable<EntityT extends VdmEntity<?>>
      Parameters:
      destination - The destination to be used as request target.
      Returns:
      The wrapped service response, exposing response headers, status code and entity references. If the HTTP response is not within healthy bounds, then one of the declared runtime exceptions will be thrown with further details.

    • toRequest

      @Nonnull public ODataRequestCreate toRequest()
      Creates an instance of the ODataRequestCreate based on the Entity class.

      The following settings are used:

      • the endpoint URL
      • the entity collection name
      • the entity JSON payload
      Specified by:
      toRequest in interface RequestBuilder<EntityT extends VdmEntity<?>>
      Returns:
      An initialized ODataRequestCreate.
      Throws:
      ODataSerializationException - If entity cannot be serialized for HTTP request.

    • withoutCsrfToken

      @Nonnull public CreateRequestBuilder<EntityT> withoutCsrfToken()
      Deactivates the CSRF token retrieval for this OData request. This is useful if the server does not support or require CSRF tokens as part of the request.
      Specified by:
      withoutCsrfToken in interface ModificationRequestBuilder<EntityT extends VdmEntity<?>>
      Returns:
      The same builder

    • getEntity

      @Nonnull protected EntityT getEntity()
      Getter for the VDM representation of the entity to be created.

    • getThis

      @Nonnull protected CreateRequestBuilder<EntityT> getThis()
      Get the reference to this instance.
      Returns:
      The FluentHelper instance.

    • withListener

      @Nonnull public CreateRequestBuilder<EntityT> withListener(@Nonnull ODataRequestListener listener)
      An error handling class that implements the error result handler interface can be attached to this request builder. This allows custom logic to be called when an error occurs in the execute method. If this method is not called, then an instance of ODataRequestListener is used. Only one handler can be attached at a time per request builder object, so calling this multiple times will replace the handler.
      Parameters:
      listener - Instance of an error handler class that implements the error result handler interface.
      Returns:
      The same request builder with its error handler set to the provided object.

    • withHeader

      @Nonnull public CreateRequestBuilder<EntityT> withHeader(@Nonnull String key, @Nullable String value)
      Description copied from interface: RequestBuilder
      Gives the option to specify custom HTTP headers. Multiple headers with the same key can be specified. The returned object allows to specify the requests the headers should be used in.
      Specified by:
      withHeader in interface RequestBuilder<BuilderT extends RequestBuilder<ResultT>>
      Parameters:
      key - Name of the (first) desired HTTP header parameter.
      value - Value of the (first) desired HTTP header parameter.
      Returns:
      A request builder to specify further headers and their intended usage.

    • withHeaders

      @Nonnull public CreateRequestBuilder<EntityT> withHeaders(@Nonnull Map<String,String> map)
      Description copied from interface: RequestBuilder
      Gives the option to specify a map of custom HTTP headers. The returned object allows to specify the requests the headers should be used in.
      Specified by:
      withHeaders in interface RequestBuilder<BuilderT extends RequestBuilder<ResultT>>
      Parameters:
      map - A map of HTTP header key/value pairs.
      Returns:
      A request builder to specify further headers and their intended usage.

    • withQueryParameter

      @Nonnull public CreateRequestBuilder<EntityT> withQueryParameter(@Nonnull String key, @Nullable String value)
      Gives the option to specify custom query parameters for the request.

      Note: It is recommended to only use this function for query parameters which are not supported by the VDM by default. Using this function to bypass request builder method calls can lead to unsupported response handling. There is no contract on the order or priority of parameters added to the request.

      Example: Use the request query option $search to reduce the result set, leaving only entities which match the specified search expression. This feature is supported in protocol OData v4. 

       new DefaultBusinessPartnerService().getAllBusinessPartner().withQueryParameter("$search", "Köln OR Cologne")

      Parameters:
      key - Name of the query parameter.
      value - Value of the query parameter.
      Returns:
      The same request builder.
