All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

Alarm

private static class Alarm.AlarmThread

extends java.lang.Thread

Alarm timer thread.

Purpose and Responsibilities

One (static) instance of the alarm thread loops infinitely executing expired alarms and sleeping until the next alarm expires and must be executed.

Concurrency

This class is thread-safe, because all read/write accesses on the scheduled alarms set are synchronized.

Special effort has been made to enable cancellations or rescheduling of alarm calls by clients within a alarm callback.
