BeginTransactionRequest

public BeginTransactionRequest()

Method Detail

getMutationKey

public Mutation getMutationKey()

Optional. Required for read-write transactions on a multiplexed session that commit mutations but don't perform any reads or queries. You must randomly select one of the mutations from the mutation set and send it as a part of this request.

Returns:

value or null for none

setMutationKey

public BeginTransactionRequest setMutationKey(Mutation mutationKey)

Optional. Required for read-write transactions on a multiplexed session that commit mutations but don't perform any reads or queries. You must randomly select one of the mutations from the mutation set and send it as a part of this request.

Parameters:

mutationKey - mutationKey or null for none

getOptions

public TransactionOptions getOptions()

Required. Options for the new transaction.

Returns:

value or null for none

setOptions

public BeginTransactionRequest setOptions(TransactionOptions options)

Required. Options for the new transaction.

Parameters:

options - options or null for none

getRequestOptions

public RequestOptions getRequestOptions()

Common options for this request. Priority is ignored for this request. Setting the priority in this `request_options` struct doesn't do anything. To set the priority for a transaction, set it on the reads and writes that are part of this transaction instead.

Returns:

value or null for none

setRequestOptions

public BeginTransactionRequest setRequestOptions(RequestOptions requestOptions)

Common options for this request. Priority is ignored for this request. Setting the priority in this `request_options` struct doesn't do anything. To set the priority for a transaction, set it on the reads and writes that are part of this transaction instead.

Parameters:

requestOptions - requestOptions or null for none

set

public BeginTransactionRequest set(String fieldName,
                                   Object value)

Overrides:
