OERA Open Source Initiative

tamhas — Fri, 29 Aug 2008 21:55:55 +0000

The OERA Open Source Initiative (OERA OSI) is a project to define, create, and refine a series of production quality components which can serve as a sound basis for those creating their own OERA implementations. The primary focus will be components which would form a portion of the Common Infrastructure portion of the standard OERA model, but we will not exclude contributions for other sorts of helper classes which might be used as part of a Data Access, Business Logic, or UI layer.

Exception and Condition Handling Classes

tamhas — Wed, 04 Oct 2006 19:31:19 +0000

One of the problems faced by ABL programmers for many years is the lack of a true exception handling mechanism in the language. By “exception handling”, we mean a mechanism by which a program encounters an error or unexpected condition then can communicate up the call stack with the purpose of:
1. Signaling that requested execution has not completed as expected;
2. Communicating any necessary information about the details of why this condition occurred; and
3. Providing a structure such that the condition is “handled” in a graceful fashion at an appropriate level in the code.

Collection and Map Classes for OOABL

tamhas — Wed, 04 Oct 2006 19:23:49 +0000

In developing a foundation framework for Object-Oriented ABL, it seems natural to consider creating a set of Collection classes since they have a broad utility in OO design in other languages. It also seems natural to consider imitating the Collection classes in Java since that is a tried and true implementation into which there has been a considerable investment of thought and effort.
