About

Prob-lo-Matic is an implementation of the GoF Chain of Responsibility pattern [GoF]. It's designed as a cross-application problem handling framework; that is, system- or user-level exceptions are caught, wrapped in a "Problem" object, and passed through a chain of handlers. The idea is to give application developers a chance to fix the error, notify people, re-try database connections, etc. More advanced applications could involve:

• The persistence of Problems to a database for tracking/reporting
• Building a knowledgebase of runtime problems and their solutions for command center technicians
• The development of "Solution" classes that map to "Problems" and fix known issues at run-time
