<br />
This is because the type and structure of framework-internal data may (in fact WILL) change over time, as the framework is developed further. But if the user access framework-internal data directly, these changes causes the user code be broken.<br />
<br />
TTCN-3 doesn't have the means to disable direct access to component definitions. Please note, that at least the &quot;top level&quot; component types definitions of the framework shall be public, as the users shall be able to extend them.<br />
<br />
The solution of the problem is to introduce visibily within components for component definitions as well:<br />
In component member definitions they mean the following:<br />
• The public modifier means that any function/testcase/altstep running on that component instance can access the member definition directly.<br />
• The private modifier means that only those functions/testcases/altsteps can access the definition which refer to the component type in its runs on clause directly. If they run on a component type extending the one containing the definition, it will not be directly visible.<br />
The friend modifier is not available within component types.<br />
<br />
<br />
In this way framework-internal data is defined within private component types as private definitions. For data manipulation set and get functions are defined within the same module, with public visibility. These can be used by the users. Also, public component type(s), extending the private one is defined that other library modules or the users can use directly or extend further.<br />

				Sorry, we have a problem with the @accessor modifyer. The problem is that private variables are used so widely that the @accessor restriction is practically impossible to introduce at this stage.<br />

@accessor in fact &quot;sort&quot; the functions/atsteps within the module (in which the component type is defined) to the ones that are allowed to directly access the private definitions and the ones which are disallowed.

				I thought we discussed this at length and made a decision. <br />
<br />
Of course, the usual pattern of using the publicly defined variables of a component does not work anymore, so this is not a backward-compatibility feature. <br />
It is a feature for the allowing to define proper APIs in the future, which at the moment is not possible.<br />
<br />
If, if I understand you correctly, you want to implicitly turn all functions inside the same module as the component containing the private variables (which, I guess, is a proprietary feature in your tool?) into implicit accessor functions for their runs on type, this incurs implicit restrictions on all functions using these functions (i.e. the previous lax component-runs-on compatibility rules cannot be used anymore).<br />
<br />
In principle, I have no problem with that, but it breaks your usual preference regarding implicitness vs. explicitness.<br />
