Examples of Chore

com.acelet.s.chore.Chore
Chore is an object contains a job and timing information. All names of variables are long. They are self-explanatory. Chore is for SuperWatchdog. "chore" is the logical term for "task". In user's manual, it is called "task", but in API and database, it is called "chore".
org.apache.hadoop.hbase.Chore
Chore is a task performed on a period in hbase. The chore is run in its own thread. This base abstract class provides while loop and sleeping facility. If an unhandled exception, the threads exit is logged. Implementers just need to add checking if there is work to be done and if so, do it. Its the base of most of the chore threads in hbase.
Don't subclass Chore if the task relies on being woken up for something to do, such as an entry being added to a queue, etc.
