Method Details

getId

com.google.protobuf.ByteString getId()

 `id` may be used to identify the transaction in subsequent
 [Read][google.spanner.v1.Spanner.Read],
 [ExecuteSql][google.spanner.v1.Spanner.ExecuteSql],
 [Commit][google.spanner.v1.Spanner.Commit], or
 [Rollback][google.spanner.v1.Spanner.Rollback] calls.

 Single-use read-only transactions do not have IDs, because
 single-use transactions do not support multiple requests.
 

bytes id = 1;

Returns:

The id.

hasReadTimestamp

boolean hasReadTimestamp()

 For snapshot read-only transactions, the read timestamp chosen
 for the transaction. Not returned by default: see
 [TransactionOptions.ReadOnly.return_read_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.return_read_timestamp].

 A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds.
 Example: `"2014-10-02T15:01:23.045123456Z"`.
 

.google.protobuf.Timestamp read_timestamp = 2;

Returns:

Whether the readTimestamp field is set.

getReadTimestamp

com.google.protobuf.Timestamp getReadTimestamp()

 For snapshot read-only transactions, the read timestamp chosen
 for the transaction. Not returned by default: see
 [TransactionOptions.ReadOnly.return_read_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.return_read_timestamp].

 A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds.
 Example: `"2014-10-02T15:01:23.045123456Z"`.
 

.google.protobuf.Timestamp read_timestamp = 2;

Returns:

The readTimestamp.

getReadTimestampOrBuilder

com.google.protobuf.TimestampOrBuilder getReadTimestampOrBuilder()

 For snapshot read-only transactions, the read timestamp chosen
 for the transaction. Not returned by default: see
 [TransactionOptions.ReadOnly.return_read_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.return_read_timestamp].

 A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds.
 Example: `"2014-10-02T15:01:23.045123456Z"`.
 

.google.protobuf.Timestamp read_timestamp = 2;

hasPrecommitToken

boolean hasPrecommitToken()

 A precommit token is included in the response of a BeginTransaction
 request if the read-write transaction is on a multiplexed session and
 a mutation_key was specified in the
 [BeginTransaction][google.spanner.v1.BeginTransactionRequest].
 The precommit token with the highest sequence number from this transaction
 attempt should be passed to the [Commit][google.spanner.v1.Spanner.Commit]
 request for this transaction.
 

.google.spanner.v1.MultiplexedSessionPrecommitToken precommit_token = 3;

Returns:

Whether the precommitToken field is set.

getPrecommitToken

MultiplexedSessionPrecommitToken getPrecommitToken()

 A precommit token is included in the response of a BeginTransaction
 request if the read-write transaction is on a multiplexed session and
 a mutation_key was specified in the
 [BeginTransaction][google.spanner.v1.BeginTransactionRequest].
 The precommit token with the highest sequence number from this transaction
 attempt should be passed to the [Commit][google.spanner.v1.Spanner.Commit]
 request for this transaction.
 

.google.spanner.v1.MultiplexedSessionPrecommitToken precommit_token = 3;

Returns:

The precommitToken.

getPrecommitTokenOrBuilder

MultiplexedSessionPrecommitTokenOrBuilder getPrecommitTokenOrBuilder()

 A precommit token is included in the response of a BeginTransaction
 request if the read-write transaction is on a multiplexed session and
 a mutation_key was specified in the
 [BeginTransaction][google.spanner.v1.BeginTransactionRequest].
 The precommit token with the highest sequence number from this transaction
 attempt should be passed to the [Commit][google.spanner.v1.Spanner.Commit]
 request for this transaction.
 

.google.spanner.v1.MultiplexedSessionPrecommitToken precommit_token = 3;
