In ISA, the memory is managed thru smart pointer because of the efficiency and simplicity of this approach. On usual systems, the O.S. also provides Processes. To free objects, the process wall is broken by ISA! But this implies some memory management adjustments.

This post is some kind of tutorial on the Last Language type system. Not just a tutorial in fact, but a discussion space to challenge the ISA type architecture.
Continue reading Overview of the LL type systemThe scope, background and foundations of ISA are now well established. It is time to examine the existing principles, the concepts and artefacts that are not useful for us. To reverse our point view in order to enumerate the existing things that must be avoided.
Continue reading Useless conceptsISA relies on the Object Oriented paradigm. Let me now join OO with our wishes. Some guidances emerge . The first one is, not surprisingly, “Everything in ISA is an Object”!
Continue reading Object Oriented GuidelinesWhat is really the SOA? Analyzing pros and cons, is this a concept usable for ISA? This post conclude that no, it isn’t. OO is more powerful and provides a wider consistancy.
However, some SOA central properties have to be incorporated in ISA. Let’s have a look to them!
Here I study the Class Object state axiom in the perspective of an incorporation in ISA. What’s about the Class life cycle ? And about the Versioning, the Grouping and the Delivery ?
Continue reading The State axiom – Part 4Third post on the object state axiom. Here I will speak about the state of the Class object and begin to define what it is. It is also question of immutability and of threaded objects.
Continue reading The State axiom – Part 3In this second post on Object state, we will see what are Fields, Relationships, Properties and Attributes; and why and how to put them all together.
Continue reading The State axiom – Part 2ISA is about the 5th computing era : The Distribution one.
When the things are done in many computing units, of many kinds, in many places, available to anyone. When the centralization is no more possible.
This post answers the question “What’s a State ?”. It also consider object life cycle and the basic Design Patterns. Finally, Eiffel’s advanced features around state are evoked.
