java.lang.Object
com.sap.cloud.sdk.datamodel.odatav4.core.FunctionRequestBuilder<SingleValueFunctionRequestBuilder<ResultT>,ResultT>
com.sap.cloud.sdk.datamodel.odatav4.core.SingleValueFunctionRequestBuilder<ResultT>
Type Parameters:
ResultT - The type of the result entity, if any.
All Implemented Interfaces:
ReadRequestBuilder<ResultT>, RequestBuilder<ResultT>, RequestBuilderExecutable<ResultT>
public class SingleValueFunctionRequestBuilder<ResultT> extends FunctionRequestBuilder<SingleValueFunctionRequestBuilder<ResultT>,ResultT>
Representation of an OData function request as a fluent interface for further configuring the request and executing it. This one handles functions where the return type is a single primitive or entity value.

    • SingleValueFunctionRequestBuilder

      public SingleValueFunctionRequestBuilder(@Nonnull String servicePath, @Nonnull String functionName, @Nonnull Class<ResultT> resultClass)
      Instantiates this request builder using the given service path to send the requests.
      Parameters:
      servicePath - The service path to direct the requests to.
      functionName - The name of the unbound function
      resultClass - The expected return type of the function.

    • SingleValueFunctionRequestBuilder

      public SingleValueFunctionRequestBuilder(@Nonnull String servicePath, @Nonnull String functionName, @Nonnull Map<String,Object> parameters, @Nonnull Class<ResultT> resultClass)
      Instantiates this request builder using the given service path to send the requests.
      Parameters:
      servicePath - The service path to direct the requests to.
      functionName - The name of the unbound function
      parameters - The parameters passed to the function.
      resultClass - The expected collection return type of the function.

  • Method Details

    • execute

      @Nonnull public ResultT execute(@Nonnull Destination destination)
      Description copied from interface: RequestBuilderExecutable
      Execute the OData request.
      Parameters:
      destination - The destination to be used as request target.
      Returns:
      The generic OData response result.

    • getResultClass

      @Nonnull protected Class<ResultT> getResultClass()

    • getThis

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

    • withListener

      @Nonnull public SingleValueFunctionRequestBuilder<ResultT> 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 SingleValueFunctionRequestBuilder<ResultT> 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 SingleValueFunctionRequestBuilder<ResultT> 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 SingleValueFunctionRequestBuilder<ResultT> 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.
