Examples of org.apache.felix.dm.impl.SerialExecutor

org.apache.felix.dm.impl.SerialExecutor

Allows you to enqueue tasks from multiple threads and then execute them on one thread sequentially. It assumes more than one thread will try to execute the tasks and it will make an effort to pick the first task that comes along whilst making sure subsequent tasks return without waiting.

This class is lock free and ensures "safe object publication" between scheduling threads and actual executing thread: if one thread T1 schedules a task, but another thread T2 actually executes it, then all the objects from the T1 thread will be "safely published" to the executing T2 thread. Safe publication is ensured because we are using a ConcurrentLinkedQueue. (see [1], chapter 3.5.3 (Safe publication idioms).
