Chronicle API C++ Client Library

An idiomatic C++ client library for the Chronicle API.

The Chronicle API serves all customer endpoints.

While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The following shows the code that you'll run in the google/cloud/chronicle/quickstart/ directory, which should give you a taste of the Chronicle API C++ client library API.

#include "google/cloud/chronicle/v1/entity_client.h"
#include "google/cloud/common_options.h"
#include "google/cloud/location.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc != 4) {
    std::cerr << "Usage: " << argv[0]
              << " project-id location-id instance-id\n";
    return 1;
  }
  auto const endpoint = "us-chronicle.googleapis.com";
  auto const location = google::cloud::Location(argv[1], argv[2]);
  auto const instance_id = std::string(argv[3]);

  namespace gc = ::google::cloud;
  namespace chronicle = ::google::cloud::chronicle_v1;

  auto client =
      chronicle::EntityServiceClient(chronicle::MakeEntityServiceConnection(
          gc::Options{}
              .set<gc::EndpointOption>(endpoint)
              .set<gc::AuthorityOption>(endpoint)));

  for (auto r : client.ListWatchlists(location.FullName() + "/instances/" +
                                      instance_id)) {
    if (!r) throw std::move(r).status();
    std::cout << r->DebugString() << "\n";
  }

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
}

Main classes

This library offers multiple *Client classes, which are listed below. Each one of these classes exposes all the RPCs for a service as member functions of the class. This library groups multiple services because they are part of the same product or are often used together. A typical example may be the administrative and data plane operations for a single product.

The library also has other classes that provide helpers, configuration parameters, and infrastructure to mock the *Client classes when testing your application.
