An idiomatic C++ client library for the Document AI Warehouse API, an integrated, cloud-based platform to store, search, organize, govern and analyze documents and their structured metadata.
While this library is GA, please note that the Google Cloud C++ client libraries do not follow Semantic Versioning.
QuickstartThe following shows the code that you'll run in the google/cloud/contentwarehouse/quickstart/
directory, which should give you a taste of the Document AI Warehouse API C++ client library API.
#include "google/cloud/contentwarehouse/v1/document_client.h"
#include <iostream>
int main(int argc, char* argv[]) try {
if (argc != 3) {
std::cerr << "Usage: " << argv[0] << " project-number location-id\n";
return 1;
}
namespace contentwarehouse = ::google::cloud::contentwarehouse_v1;
auto client = contentwarehouse::DocumentServiceClient(
contentwarehouse::MakeDocumentServiceConnection());
auto const parent =
std::string{"projects/"} + argv[1] + "/locations/" + argv[2];
for (auto r : client.SearchDocuments(parent)) {
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.
contentwarehouse_v1::DocumentServiceClient
contentwarehouse_v1::DocumentLinkServiceClient
contentwarehouse_v1::DocumentSchemaServiceClient
contentwarehouse_v1::RuleSetServiceClient
contentwarehouse_v1::SynonymSetServiceClient
