Detailed Description

A single request to a single service.

Request objects are created using Service::createRequest() or Service::createAuthorizationRequest(). They are used with Session::sendRequest() or Session::sendAuthorizationRequest().

The Request object contains the parameters for a single request to a single service. Once a Request has been created its fields can be populated directly using the convenience functions set() and append() functions or using the Element interface on the Element returned by asElement().

The schema for the Request can be queried using the Element interface on the Element returned by asElement().

Request objects cannot be duplicated. Copying a Request causes the original Request to become invalid. The API provides support for common idioms which require a normal copy constructor. For example, you can write the following code.

Request request(service.createRequest("operationName"));

However, if you write this requestOne will become invalid and unusable.

Request requestOne(service.createRequest("operationName"));
Request requestTwo(requestOne);
// At this point requestOne is no longer valid

This should be written as follows.

Request requestOne(service.createRequest("operationName"));
Request requestTwo(service.createRequest("operationName"));

If level is specified, optionally specify spacesPerLevel, the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level).
