Method Detail

initializeEnvironment

public ConcurrentEnvironment initializeEnvironment(Thread key,
                                                   Thread.UncaughtExceptionHandler params)

Specified by:

initializeEnvironment in class ConcurrencyServiceAbstract

maxThreads

protected int maxThreads()

isMultiThreaded

public boolean isMultiThreaded()

Overrides:

runTimeout

public void runTimeout(Runnable cmd,
                       int millisToWait)

Description copied from interface: ConcurrencyService

Wait (at least) a given number of milliseconds to perform a task. Exact timing promises are not made, so if you need an exact timing in a concurrent environment, schedule your deadline 10-50 millis early, or even better, track latency (how much later you are called then requested) and adjust your timeouts accordingly.

Parameters:

cmd - - The command to run.

millisToWait - - A minimum of milliseconds to wait.

newLock

public AsyncLock newLock()

Returns:

A lock suitable for the environment in which you are running. We may extend the Lock interface, and require subclasses that offer a given, small set of additional functionality.
