Class Summary

ArrayEnumeration	This class provides a way to enumerate over an array.
ArraySet	Implementation of a simple Set based on an array.
BackgroundThread	This thread allows a runnable to run continously until the runnable is garbage collected.
Configuration	Provides basic configuration for Tyrex components based on the tyrex.config configuration file.
FastThreadLocal	This is an efficient implementation of ThreadLocal which uses a background thread to remove stale thread entries, doing away with the inefficiencies of WeakHashMap.
HashIntTable	This class provides unsynchronized hash get, put, remove and increment of int values.
Messages
Messages.EmptyResourceBundle
Primes	This class provides a single service.
Version	Prints version information to the console.

Configuration, Messages and Logging

Configuration provides basic configuration for Tyrex based on the tyrex.config configuration file. Several Tyrex services rely on this configuration file.

The member variable Configuration.verbose determines whether Tyrex should emit verbose information messages, which can be used for troubleshooting purposes. This class also provides access to a random number generator.

tyrex..util.Logger.

tyrex.util.LoggerPrintWriter implements a PrintWriter using a Log4J category. Connectors and other J2EE service providers require a PrintWriter in order to log messages, and rely on this object as an adapter for the Log4J category.

Messages performs formatting of messages based on the current locale, using a message resource file. This class is often used by exceptions and logging messages to perform formatting based on an actual string contents that is obtained form a resource file, depending on the current locale.

Misc

FastThreadLocal is an optimized implementation of ThreadLocal which uses a background thread to remove stale thread entries, doing away with the inefficiencies of WeakHashMap.
