Detailed Description

Transactions facade.

This class is implemented as a reference to an implementation so copying of this class instance will only create another reference to the same underlying object. Underlying object will be released automatically once all the instances are destructed.

Constructor & Destructor Documentation

Transactions() [1/2]

ignite::transactions::Transactions::Transactions

(

ignite::common::concurrent::SharedPointer< impl::transactions::TransactionsImpl >

impl

)

Constructor.

Internal method. Should not be used by user.

Parameters

impl	Implementation.

Transactions() [2/2]

ignite::transactions::Transactions::Transactions

(

const Transactions &

other

)

Copy constructor.

Parameters

other

Other instance.

Member Function Documentation

GetMetrics() [1/2]

TransactionMetrics ignite::transactions::Transactions::GetMetrics

(

)

Get transaction metrics.

Returns

Metrics instance.

GetMetrics() [2/2]

TransactionMetrics ignite::transactions::Transactions::GetMetrics

(

IgniteError &

err

)

Get transaction metrics.

Parameters

err

Error.

Returns

Metrics instance. Returned instance is not valid if an error occurred during the operation.

GetTx()

Transaction ignite::transactions::Transactions::GetTx

(

)

Get active transaction for the current thread.

Returns

Active transaction for current thread. Returned instance is not valid if there is no active transaction for the thread.

operator=()

Transactions & ignite::transactions::Transactions::operator=

(

const Transactions &

other

)

Assignment operator.

Parameters

other

Other instance.

Returns

This.

TxStart() [1/6]

Transaction ignite::transactions::Transactions::TxStart

(

)

Start new transaction with default isolation, concurrency and timeout.

Returns

New transaction instance.

TxStart() [2/6]

Transaction ignite::transactions::Transactions::TxStart

(

IgniteError &

err

)

Start new transaction with default isolation, concurrency and timeout.

Parameters

err

Error.

Returns

New transaction instance.

TxStart() [3/6]

Transaction ignite::transactions::Transactions::TxStart	(	TransactionConcurrency::Type	concurrency,
		TransactionIsolation::Type	isolation
	)

Starts new transaction with the specified concurrency and isolation.

Parameters

concurrency	Concurrency.

Returns

New transaction instance.

TxStart() [4/6]

Transaction ignite::transactions::Transactions::TxStart	(	TransactionConcurrency::Type	concurrency,
		TransactionIsolation::Type	isolation,
		IgniteError &	err
	)

Starts new transaction with the specified concurrency and isolation.

Parameters

concurrency	Concurrency.

Returns

New transaction instance.

TxStart() [5/6]

Transaction ignite::transactions::Transactions::TxStart	(	TransactionConcurrency::Type	concurrency,
		TransactionIsolation::Type	isolation,
		int64_t	timeout,
		int32_t	txSize
	)

Starts transaction with specified isolation, concurrency, timeout, and number of participating entries.

Parameters

concurrency	Concurrency.
isolation	Isolation.
timeout	Timeout. Zero if for infinite timeout.
txSize	Number of entries participating in transaction (may be approximate).

Returns

New transaction instance.

Parameters

concurrency	Concurrency.
isolation	Isolation.
timeout	Timeout. Zero if for infinite timeout.
txSize	Number of entries participating in transaction (may be approximate).
err	Error.

Returns

New transaction instance.
