Law of Reversibility of Attributes


Law of Reversibility of Attributes

I’ve come up with a simple law called Law of Reversability of Attributes.  It’s based on the physics law of a similar name.  Basically what the law means is that the inverse of a transformation should result in a return to the original state.

The Law of Reversibility of Attributes is defined as:

For a given state of an object; when a attribute’s value is changed, the inverse of that value, when applied to that attribute, will result in the object returning to its original state.

I say “attribute” rather than “property” to encompass methods that imply setting of attributes.  So, for example

            myObject.BooleanValue = !myObject.BooleanValue;

            myObject.BooleanValue = !myObject.BooleanValue;




means myObject will be in the same state after the second line of code than it was before the first line of code.

[UPDATE: interestingly, after I wrote this post–which was delay-published–Bill Wagner wrote a great article on a very similar topic in Visual Studio Magazine]
