Constructor Detail

TransactionSelector

public TransactionSelector()

Method Detail

getBegin

public TransactionOptions getBegin()

Begin a new transaction and execute this read or SQL query in it. The transaction ID of the new transaction is returned in ResultSetMetadata.transaction, which is a Transaction.

Returns:

value or null for none

setBegin

public TransactionSelector setBegin(TransactionOptions begin)

Begin a new transaction and execute this read or SQL query in it. The transaction ID of the new transaction is returned in ResultSetMetadata.transaction, which is a Transaction.

Parameters:

begin - begin or null for none

getId

public String getId()

Execute the read or SQL query in a previously-started transaction.

Returns:

value or null for none

See Also:

decodeId()

decodeId

public byte[] decodeId()

Execute the read or SQL query in a previously-started transaction.

Returns:

Base64 decoded value or null for none

Since:

1.14

See Also:

getId()

setId

public TransactionSelector setId(String id)

Execute the read or SQL query in a previously-started transaction.

Parameters:

id - id or null for none

See Also:

#encodeId()

encodeId

public TransactionSelector encodeId(byte[] id)

Execute the read or SQL query in a previously-started transaction.

Since:

1.14

See Also:

The value is encoded Base64 or {@code null} for none.

getSingleUse

public TransactionOptions getSingleUse()

Execute the read or SQL query in a temporary transaction. This is the most efficient way to execute a transaction that consists of a single SQL query.

Returns:

value or null for none

setSingleUse

public TransactionSelector setSingleUse(TransactionOptions singleUse)

Execute the read or SQL query in a temporary transaction. This is the most efficient way to execute a transaction that consists of a single SQL query.

Parameters:

singleUse - singleUse or null for none

set

public TransactionSelector set(String fieldName,
                               Object value)

Overrides:

set in class com.google.api.client.json.GenericJson

clone

public TransactionSelector clone()

Overrides:

clone in class com.google.api.client.json.GenericJson
