Example 23 with InputObjectState

use of com.arjuna.ats.arjuna.state.InputObjectState in project narayana by jbosstm.

the class OptimisticLockManager method loadState.

/*
     * Lock and load the concurrency control state. First we grab the semaphore
     * to ensure exclusive access and then we build the held lock list by
     * retreiving the locks from the lock repository. If there is only one
     * server we do not bother doing this since all the locks can stay in the
     * server's memory. This is yet another consequence of not having
     * multi-threaded servers. Does not require synchronized since it can only
     * be called from other synchronized methods.
