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.

Thesis: Not to be generic At first, I didn’t want to include generics in LL. This is mainly for two reasons. First, because it is really hard to conceive and understand a generic algorithm. This goes at contrary of the Wish N°5 – Simple and freed of experts. In my professional life, I have often …
Continue reading To be or not to be GenericWhat are the major guidelines for LL? Simple (as Basic and PHP), Powerfull (like C++ or Smalltalk), Consistent (as OO is), Efficient (as C++ and Python), Dynamic but not messy, Seamlessly to suit to the whole software life cycle.
Continue reading LL basics and syntaxHow to express ISA ? The conclusion here is that building a first round of LL is the best answer. A warm up lap before the real start of the ISA solutions.
Continue reading What language to express ISA?What 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 2This 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.
Continue reading The State axiom – Part 1What are the Identity axiom consequences ? Here is a list of studied subject by this post: Addressing, Unitarity, Uniqueness, Ubiquity, Versioning.
