Service Description: The Cloud Firestore service.

This service exposes several types of comparable timestamps:

* `create_time` - The time at which a document was created. Changes only when a document is deleted, then re-created. Increases in a strict monotonic fashion. * `update_time` - The time at which a document was last updated. Changes every time a document is modified. Does not change when a write results in no modifications. Increases in a strict monotonic fashion. * `read_time` - The time at which a particular state was observed. Used to denote a consistent snapshot of the database or the time at which a Document was observed to not exist. * `commit_time` - The time at which the writes in a transaction were committed. Any read with an equal or greater `read_time` is guaranteed to see the effects of the transaction.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 
 try (FirestoreClient firestoreClient = FirestoreClient.create()) {
   Document document = Document.newBuilder().build();
   DocumentMask updateMask = DocumentMask.newBuilder().build();
   Document response = firestoreClient.updateDocument(document, updateMask);
 }
 
 

Note: close() needs to be called on the firestoreClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
3. A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of FirestoreSettings to create(). For example:

To customize credentials:

 
 FirestoreSettings firestoreSettings =
     FirestoreSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 FirestoreClient firestoreClient =
     FirestoreClient.create(firestoreSettings);
 
 

To customize the endpoint:

 
 FirestoreSettings firestoreSettings =
     FirestoreSettings.newBuilder().setEndpoint(myEndpoint).build();
 FirestoreClient firestoreClient =
     FirestoreClient.create(firestoreSettings);

listCollectionIdsPagedCallable

public final com.google.api.gax.rpc.UnaryCallable<ListCollectionIdsRequest,FirestoreClient.ListCollectionIdsPagedResponse> listCollectionIdsPagedCallable()

Lists all the collection IDs underneath a document.

Sample code:

 try (FirestoreClient firestoreClient = FirestoreClient.create()) {
   String formattedParent = AnyPathName.format("[PROJECT]", "[DATABASE]", "[DOCUMENT]", "[ANY_PATH]");
   ListCollectionIdsRequest request = ListCollectionIdsRequest.newBuilder()
     .setParent(formattedParent)
     .build();
   ApiFuture<ListCollectionIdsPagedResponse> future = firestoreClient.listCollectionIdsPagedCallable().futureCall(request);
   // Do something
   for (String element : future.get().iterateAll()) {
     // doThingsWith(element);
   }
 }
