Encapsulation

[wl]

Hi,


I am reading from a TCP socket but instead of using the prefixed mode I'm relying on my own message structure: I have implemented this as a method in a code module which gets a byte as parameter and adds it to a stringbuilder etc.

Between the calls to this method I need to keep state (am I reading the header info similar as the prefix bytes, or reading the message etc). Currently the state (and other variables) is stored as a variable in the global_process.

However, what if the same code gets executed multiple times (different threads) ? The only solution seems to keep the state variables in the threading code.

In Object-Oriented code I would have created a class that kept the state variables as private variables. Since OO has not yet been implemented in B4A, what would be the best approach ?

I was thing of a map with all variables I need to keep state (a map can also contain a list and other objects ?) so that at least I only need to store 1 variable outside the code module ?

Any other suggestions ?

Thanks

I just found this thread: http://www.b4x.com/forum/basic4android-updates-questions/12516-coding-without-classes.html#post70468

Would it be possible to include a StringBuilder, Map, List, ... as an element in a custom type ?

Perhaps also some kind of function/method pointer Then I would have my light-weight OO

To answer myself: it seems type structures can contain objects. Unfortunately, these can not be passed as params to functions which makes them unusable for this purpose...

But still: if someone else has another idea of how implement some method of encapsulation in B4A ?

That is not correct. You can pass any type as a parameter.

Yes, it seemsin fact I was wrong. Thanks !
