Quickstart
The following shows the code that you'll run in thegoogle/cloud/memcache/quickstart/directory, which should give you a taste of the Cloud Memorystore for Memcached API C++ client library API.
#include "google/cloud/memcache/v1/cloud_memcache_client.h"
#include "google/cloud/location.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 2) {
std::cerr << "Usage: " << argv[0] << " project-id\n";
return 1;
}
auto const location = google::cloud::Location(argv[1], "-");
namespace memcache = ::google::cloud::memcache_v1;
auto client =
memcache::CloudMemcacheClient(memcache::MakeCloudMemcacheConnection());
for (auto i : client.ListInstances(location.FullName())) {
if (!i) throw std::move(i).status();
std::cout << i->DebugString() << "\n";
}
return 0;
} catch (google::cloud::Status const& status) {
std::cerr << "google::cloud::Status thrown: " << status << "\n";
return 1;
}
Main classes
The main class in this library ismemcache_v1::CloudMemcacheClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mockmemcache_v1::CloudMemcacheClientwhen testing your application.
