Method Detail

saveBOImpl

TransactionAnswer saveBOImpl(Transaction tx,
                             int lockTimeout,
                             int retries,
                             Benutzer onBehalfOf)

Persists the changes recorded in the passed Transaction tx to the database.

Parameters:

tx - the Transaction to save

lockTimeout - time to wait in seconds until a locking error is reported in case some object is already locked by another thread; defaults to -1. Zero or less for no waiting, i.e. immediate timeout (or rather the defined lock-timeout of JDO, which defaults to 30s), an infinite value for no timeout.

retries - an int reflecting the number of retries that shall be attempted before saving is aborted

onBehalfOf - the Benutzer on whose behalf to save

Returns:

the TransactionAnswer resulting from the save process, or null if no saving was actually done for some reason

saveBOImpl

TransactionAnswer saveBOImpl(Transaction tx,
                             int lockTimeout,
                             int retries)

Persists the changes recorded in the passed Transaction tx to the database.

Parameters:

tx - the Transaction to save

lockTimeout - time to wait in seconds until a locking error is reported in case some object is already locked by another thread; defaults to -1. Zero or less for no waiting, i.e. immediate timeout (or rather the defined lock-timeout of JDO, which defaults to 30s), an infinite value for no timeout.

retries - an int reflecting the number of retries that shall be attempted before saving is aborted

Returns:

the TransactionAnswer resulting from the save process, or null if no saving was actually done for some reason

saveBOImpl

TransactionAnswer saveBOImpl(Transaction tx,
                             int lockTimeout)

Persists the changes recorded in the passed Transaction tx to the database.

Parameters:

tx - the Transaction to save
