Dan,

4Test doesn't have static variables (hopefully not yet)
There are (at least) 2 ways to achieve what you want to do :
(1) use a global.
(2) Use FileWriteValue and FileReadValue.

There is no equivalent to static inside a function.  However, you can
use private to limit the scope of a variable to the file in which it is
declared  (_4Test Language Reference_ "Language Summary -
Declarations").

So if you can isolate the function in it's own .inc file, then you can
get the effect you want by declaring the variable to be private outside
the scope of the function.

/* A.inc */
//this is available to everything that includes A.inc
integer myA = 1 ; 
//this can only be used inside A.inc
private integer myB = 2 ; 

ATest ()
{
	print ( myA ) ;
	//OK, ATest is inside A.inc
	print ( myB ) ; 
}

/* B.inc */
BTest ()
{
	//OK, myA is global
	print ( myA ) ; 
	//Compile Error - myB not in scope here
	print ( myB ) ; 
}

/* Main.t */
use "A.inc" ;
use "B.inc" ;

main ()
{
	ATest () ; //Fine
	
	//Compile Error, B.inc doesn't compile
	BTest () ; 
	
	print ( myA ) ;
	
	//Compile Error - myB not in scope here
	print ( myB ) ; 
}

Here's an example using a privately declared winclass

/* C.inc */
private winclass C { integer m = 2 ; }

//A "constructor" [actually, a factory method, but why quibble]
window GetC( string sTag ) { return C(sTag) ; }
	
/* Main.t */
use "B.inc" ;

main ()
{
	//doesn't compile - winclass C is private
	//window theC = C("theB") ; 

	//Access via the factory
	window theOtherC = GetC("theOtherC") ; 
	
	//class members are available!
	print ( theOtherC.m ) ; 
}

As best I can tell, private is only allowed when working in the file
scope.  It doesn't compile inside of functions, or inside of classes.
If you want to create a private class member, for instance, you are
going to have to be clever - it can be done, but it is more effort than
it is worth.

Topic No. 4

Topic No. 4
Message-ID: 

Hi

I've been trying to find out if there is an elegant way of defining 
constructors for user defined classes.

This is the way we are doing it now:

//the class definition
winclass MyClass
{
	string sInit	
}

//the constructor
window MyClassConst(string sString)
{
	window Temp
	Temp = MyClass()
	Temp.sInit = sString
	return (Temp)
}


//code creating a new object via the constructor
main()
{
	window wClass = MyClassConst("teststring")
	Print (wClass.sInit)		//prints the string "teststring"
}

While this works, I find it a bit odd since,  in essence, the 
"constructor" is not really a constructor but a global function. I 
would rather do something like C++ where the constructor(s) is/are 
defined within the class.

The way an object is created:
	window myObject = MyClass()

and the fact that there are brackets at the end of MyClass, seems to 
imply that parameters can be passed, eg MyClass("teststring").  I 
tried that, compiled and ran it and there were not problems.  However, 
I'm still stuck trying to capture that parameter from inside the 
class.  Does anyone know if this is doable and, if so, how?
