Classes
firebase::firestore::AggregateQuery	A query that calculates aggregations over an underlying query.
firebase::firestore::AggregateQuerySnapshot	The results of executing an AggregateQuery.
firebase::firestore::CollectionReference	A CollectionReference can be used for adding documents, getting document references, and querying for documents (using the methods inherited from `Query`).
firebase::firestore::DocumentChange	A DocumentChange represents a change to the documents matching a query.
firebase::firestore::DocumentReference	A DocumentReference refers to a document location in a Firestore database and can be used to write, read, or listen to the location.
firebase::firestore::DocumentSnapshot	A DocumentSnapshot contains data read from a document in your Firestore database.
firebase::firestore::FieldPath	A FieldPath refers to a field in a document.
firebase::firestore::FieldValue	A field value represents variant datatypes as stored by Firestore.
firebase::firestore::Filter	A Filter represents a restriction on one or more field values and can be used to refine the results of a Query.
firebase::firestore::Firestore	Entry point for the Firebase Firestore C++ SDK.
firebase::firestore::GeoPoint	An immutable object representing a geographical point in Firestore.
firebase::firestore::ListenerRegistration	Represents a listener that can be removed by calling Remove().
firebase::firestore::LoadBundleTaskProgress	Represents a progress update or the final state from loading bundles.
firebase::firestore::Query	A Query which you can read or listen to.
firebase::firestore::QuerySnapshot	A QuerySnapshot contains zero or more DocumentSnapshot objects.
firebase::firestore::SetOptions	An options object that configures the behavior of Set() calls.
firebase::firestore::Settings	Settings used to configure a Firestore instance.
firebase::firestore::SnapshotMetadata	Metadata about a snapshot, describing the state of the snapshot.
firebase::firestore::Transaction	Transaction provides methods to read and write data within a transaction.
firebase::firestore::TransactionOptions	Options to customize transaction behavior for `Firestore.runTransaction()`.
firebase::firestore::WriteBatch	A write batch is used to perform multiple writes as a single atomic unit.

Enumerations

AggregateSource

 AggregateSource

The sources from which AggregateQuery::Get can retrieve its results.

Properties

Properties
`kServer`	Perform the aggregation on the server and download the result. The result received from the server is presented, unaltered, without considering any local state. That is, documents in the local cache are not taken into consideration, neither are local modifications not yet synchronized with the server. Previously-downloaded results, if any, are not used. Every request using this source necessarily involves a round trip to the server. The AggregateQuery will fail if the server cannot be reached, such as if the client is offline.

Error

 Error

Error codes used by Cloud Firestore.

The codes are in sync across Firestore SDKs on various platforms.

Properties
`kErrorAborted`	The operation was aborted, typically due to a concurrency issue like transaction aborts, etc.
`kErrorAlreadyExists`	Some document that we attempted to create already exists.
`kErrorCancelled`	The operation was cancelled (typically by the caller).
`kErrorDataLoss`	Unrecoverable data loss or corruption.
`kErrorDeadlineExceeded`	Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.
`kErrorFailedPrecondition`	Operation was rejected because the system is not in a state required for the operation's execution.
`kErrorInternal`	Internal errors. Means some invariants expected by underlying system has been broken. If you see one of these errors, something is very broken.
`kErrorInvalidArgument`	Client specified an invalid argument. Note that this differs from FailedPrecondition. InvalidArgument indicates arguments that are problematic regardless of the state of the system (e.g., an invalid field name).
`kErrorNotFound`	Some requested document was not found.
`kErrorOk`	The operation completed successfully.
`kErrorOutOfRange`	Operation was attempted past the valid range.
`kErrorPermissionDenied`	The caller does not have permission to execute the specified operation.
`kErrorResourceExhausted`	Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
`kErrorUnauthenticated`	The request does not have valid authentication credentials for the operation.
`kErrorUnavailable`	The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.
`kErrorUnimplemented`	Operation is not implemented or not supported/enabled.
`kErrorUnknown`	Unknown error or an error from a different error domain.
