other parts of the library involved in Value construction. For example, Mutation.WriteBuilder#set(String) returns a binder to bind a column value, and
Statement#bind(String) returns a binder to bind a parameter to a value. |
Interfaces
| Interface | Description |
|---|---|
| com.google.cloud.spanner.AsyncResultSet | Interface for result sets returned by async query methods. |
| com.google.cloud.spanner.AsyncResultSet.ReadyCallback | Interface for receiving asynchronous callbacks when new data is ready. See AsyncResultSet#setCallback(Executor, ReadyCallback). |

See TransactionContext for a description of transaction semantics.
At any point in time there can be at most one active transaction in this manager. When that |
| com.google.cloud.spanner.AsyncTransactionManager.AsyncTransactionFunction | Each step in a transaction chain is defined by an AsyncTransactionFunction. It receives a TransactionContext and the output value of the previous transaction step as its input parameters. The method should return an ApiFuture that will return the result of this step. |
| com.google.cloud.spanner.AsyncTransactionManager.AsyncTransactionStep | AsyncTransactionStep is returned by TransactionContextFuture#then(AsyncTransactionFunction, Executor) and AsyncTransactionStep#then(AsyncTransactionFunction, Executor) and allows transaction steps that should be executed serially to be chained together. Each step can contain one or more statements that may execute in parallel. |
| com.google.cloud.spanner.AsyncTransactionManager.CommitTimestampFuture | ApiFuture that returns the commit Timestamp of a Cloud Spanner transaction that is executed using an AsyncTransactionManager.

implicitly bound to a Session and therefore a particular Database. |
| com.google.cloud.spanner.ReadOnlyTransaction | A transaction type that provides guaranteed consistency across several reads, but does not allow writes. Snapshot read-only transactions can be configured to read at timestamps in the past. Snapshot read-only transactions do not need to be committed. |
| com.google.cloud.spanner.ResultSet |
Provides access to the data returned by a Cloud Spanner read or query. ResultSet allows a
single row to be inspected at a time through the methods from the StructReader interface,
in the order that the rows were returned by the read or query. The result set can be positioned
over the next row, if one exists, by calling #next(); this method returns false |
| com.google.cloud.spanner.Session |
A Session can be used to perform transactions that read and/or modify data in a Cloud
Spanner database.
Sessions can only execute one transaction at a time. To execute multiple concurrent |
| com.google.cloud.spanner.Spanner | An interface for Cloud Spanner. Typically, there would only be one instance of this for the lifetime of the application which must be closed by invoking #close() when it is no longer needed. Failure to do so may result in leaking session resources and exhausting session quota. |
| com.google.cloud.spanner.SpannerFactory |
Factory to create instance of Spanner. |
| com.google.cloud.spanner.SpannerOptions.CallContextConfigurator | CallContextConfigurator can be used to modify the ApiCallContext for one or more specific RPCs. This can be used to set specific timeout value for RPCs or use specific CallCredentials for an RPC. The CallContextConfigurator must be set as a value on the Context using the SpannerOptions#CALL_CONTEXT_CONFIGURATOR_KEY key. |
| com.google.cloud.spanner.SpannerOptions.CallCredentialsProvider | Interface that can be used to provide CallCredentials to SpannerOptions. |

| com.google.cloud.spanner.SpannerOptions.SpannerEnvironment | The environment to read configuration values from. The default implementation uses environment variables. |
| com.google.cloud.spanner.StructReader |
A base interface for reading the fields of a STRUCT. The Cloud Spanner yields
StructReader instances as one of the subclasses ResultSet or Struct, most
commonly as the result of a read or query operation. At any point in time, a StructReader
provides access to a single tuple of data comprising multiple typed columns. Each column may have |
| com.google.cloud.spanner.TransactionContext | Context for a single attempt of a locking read-write transaction. This type of transaction is the only way to write data into Cloud Spanner; Session#write(Iterable) and Session#writeAtLeastOnce(Iterable) use transactions internally. These transactions rely on pessimistic locking and, if necessary, two-phase commit. Locking read-write transactions may abort, requiring the application to retry. However, the interface exposed by TransactionRunner eliminates the need for applications to write retry loops explicitly. |
| com.google.cloud.spanner.TransactionManager |
An interface for managing the life cycle of a read write transaction including all its retries.
See TransactionContext for a description of transaction semantics.
At any point in time there can be at most one active transaction in this manager. When that |
| com.google.cloud.spanner.TransactionRunner |
An interface for executing a body of work in the context of a read-write transaction, with
retries for transaction aborts. See TransactionContext for a description of transaction
semantics. TransactionRunner instances are obtained by calling DatabaseClient#readWriteTransaction(TransactionOption...).
|
| com.google.cloud.spanner.TransactionRunner.TransactionCallable | A unit of work to be performed in the context of a transaction. |

|---|---|
| com.google.cloud.spanner.AbortedDueToConcurrentModificationException | Exception thrown by a Connection when a database operation detects that a transaction has aborted and an internal retry failed because of a concurrent modification.
