libcommons-discovery-java - 0.5-4 main

The Discovery Component is about discovering, or finding,
implementations for pluggable interfaces. It provides facilities
instantiating classes in general, and for lifecycle management of
singleton (factory) classes.
.
Fundamentally, Discovery locates classes that implement a given Java
interface. The discovery pattern, though not necessarily this package,
is used in many projects including JAXP (SaxParserFactory and others)
and commons-logging (LogFactory). By extracting this pattern, other
projects can (re)use it and take advantage of improvements to the
pattern as Discovery evolves.
.
Discovery improves over previous implementations by establishing
facilities for working within managed environments. These allow
configuration and property overrides without appealing to the global
System properties (which are scoped across an entire JVM).
