Method Detail

getTransaction

public abstract AsyncTransaction getTransaction()

Returns:

the transaction appropriate to this transaction state, or null if there is no transaction.

transactionless

@Deprecated
public abstract ObjectifyImpl transactionless(ObjectifyImpl parent)

Deprecated.

Parameters:

parent - is the parent objectify instance; the one being transitioned from

Returns:

an Objectify instance that is suitable for transactionless execution. In the case of a transactor which is not in a transaction, probably this is the same as getObjectify().

execute

public abstract <R> R execute(ObjectifyImpl parent,
                              TxnType txnType,
                              Work<R> work)

See Also:

Objectify.execute(TxnType, Work)

transactionless

public abstract <R> R transactionless(ObjectifyImpl parent,
                                      Work<R> work)

Objectify.transactionless(Work)

transact

public abstract <R> R transact(ObjectifyImpl parent,
                               Work<R> work)

See Also:

Objectify.transact(Work)

transactNew

public abstract <R> R transactNew(ObjectifyImpl parent,
                                  int limitTries,
                                  Work<R> work)

Parameters:

ofy -
