Interface Scheduler

All Known Implementing Classes:

CompoundScheduler

public interface Scheduler

An interface for interacting with an ExecutorService. A thread pool (ExecutorService) often encapsulates a set of background tasks. In many concurrent designs, these background tasks are themselves created and scheduled for execution by special background tasks dedicated to finding and scheduling the work. This interface is an abstraction of that scheduling task.
