Class CloudDatastoreRemoteServiceConfig (2.0.0) 

public abstract class CloudDatastoreRemoteServiceConfig

User-configurable global properties of Cloud Datastore.

Code not running in App Engine Standard can use the Cloud Datastore API by making a single call to #setConfig before accessing any other classes from com.google.appengine.api. For example:


 public static void main(Strings[] args) {
   CloudDatastoreRemoteServiceConfig config = CloudDatastoreRemoteServiceConfig.builder()
       .appId(AppId.create(Location.US_CENTRAL, "my-project-id"))
       .build();
   CloudDatastoreRemoteServiceConfig.setConfig(config);
   DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
   ...
 }

Outside of tests, the config should not be cleared once it has been set. In tests, the config can be cleared by calling #clear:


 {@literal @}Before
 public void before() {
   CloudDatastoreRemoteServiceConfig config = CloudDatastoreRemoteServiceConfig.builder()
       .appId(AppId.create(Location.US_CENTRAL, "my-project-id"))
       .emulatorHost(...)
       .build();
   CloudDatastoreRemoteServiceConfig.setConfig(config);
 }

 {@literal @}After
 public void after() {
   CloudDatastoreRemoteServiceConfig.clear();
 }

By default, this configuration uses application-default credentials.
