Method Detail

acquireLock

public Object acquireLock(Order order)

Note that although this method accepts an Order parameter, it does not use it in any way. This session-based lock manager implementation will prevent all operations that are identified as requiring a lock from happening in parallel. Instead, it will execute them sequentially as locks are released from previous implementations.
