Constructor Detail

LockedExecutor

public LockedExecutor(Sync mutex)
Create a new LockedExecutor that relies on the given mutual exclusion lock.

Parameters: mutex Any mutual exclusion lock. Standard usage is to supply an instance of Mutex, but, for example, a Semaphore initialized to 1 also works. On the other hand, many other Sync implementations would not work here, so some care is required to supply a sensible synchronization object.
