bool OSB_DB::PersCreditGw::lock	(	const Session &	session,
		const OSB_LIB::PersCredit::Oid &	oid
	)

Lock the personalized credit.

The caller should commit or rollback after use this method.
This function doesn't have "nowait" argument. Because it will return true only if the lock is setted by itself, if the table has already been setted, call lock(...) with blocking will cause hang.
Note: This is not so nice because of the "not care" strategy. That means we don't care who lock the table and who unlock it.

Exceptions:

throws OsbException(172) if id mismatch.

PersCreditGw& OSB_DB::PersCreditGw::operator=

const PersCreditGw &

[private]

Prevent assignment: Assignment not implemented.

bool OSB_DB::PersCreditGw::unlock	(	const Session &	session,
		const OSB_LIB::PersCredit::Oid &	oid,
		bool	nowait
	)

Unlock the personalized credit.

Unlock() does not commit. However, other sessions see the lock as released only after the transaction which unlocked it is completed.
Calling unlock() for a lock which is not held has no effect.
If unlock() is called in blocking mode from a session other than that which acquired the lock and before the locker commits, then unlock will block until the locker completes its transaction. If unlock() is called in non-blocking mode, it returns false in this case.

Parameters:

	session	Database session to use.
	oid	Unique id of personalized credit.
	nowait	If the argument is false (blocking mode) then unlock() waits for the database resource to be released if it is busy. If it is true (non-blocking mode), unlock() immediately returns false if the lock could not be released because the database resource was busy.

Returns:

True if the lock was not set or was set and successfully released (or the credit does not exist in the database).
False if unlock() was called in non-blocking mode and the lock could not be released.

bool OSB_DB::PersCreditGw::updPersCredit	(	const Session &	session,
		const OSB_LIB::PersCredit &	persCredit
	)

	session	Database session to use.
	persCredit	Personalized credit to be updated.

Exceptions:

	OsbException(169)	if currency code mismatch.
	OsbException(172)	if id mismatch.

Returns:

True if success.
