Method Detail

getLockMode

LockMode getLockMode()

Get the lock mode.

Returns:

the lock mode.

setLockMode

Session.LockRequest setLockMode(LockMode lockMode)

Specify the LockMode to be used. The default is LockMode.none.

Parameters:

lockMode - The lock mode to use for this request

Returns:

this LockRequest instance for operation chaining.

getTimeOut

int getTimeOut()

Get the timeout setting.

Returns:

timeout in milliseconds, -1 for indefinite wait and 0 for no wait.

setTimeOut

Session.LockRequest setTimeOut(int timeout)

Specify the pessimistic lock timeout (check if your dialect supports this option). The default pessimistic lock behavior is to wait forever for the lock.

Parameters:

timeout - is time in milliseconds to wait for lock. -1 means wait forever and 0 means no wait.

Returns:

this LockRequest instance for operation chaining.

getScope

boolean getScope()

Check if locking is cascaded to owned collections and relationships.

Returns:

true if locking will be extended to owned collections and relationships.

setScope

Session.LockRequest setScope(boolean scope)

Specify if LockMode should be cascaded to owned collections and relationships. The association must be mapped with cascade="lock" for scope=true to work.

Parameters:

scope - true to cascade locks; false to not.

Returns:

this, for method chaining
