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.

execute

public void execute(java.lang.Runnable command)
             throws java.lang.InterruptedException

Execute the given command directly in the current thread, within the supplied lock.

Specified by:

execute in interface Executor

java.lang.InterruptedException
