public class SpyLog

extends SpyObject

The Spy Asynchronous logger.

SpyLog is an implementation of an asynchronous logger that allows one to have multiple points of input into a single queueing system that runs in its own thread recording the logs.

If this doesn't sound immediately obvious to you, imagine having a transactional system that logs into a database without slowing down the transactions. SpyLog gives you the ability to get a log entry out of your way quickly, to be permanently recorded later.
