[news.eclipse.modeling.mdt.ocl] OCLExpressions

[mary@**********.com (mary)]

Hello, 
I am new to OCL and I am trying to use it with QVT. I want to create an 
OCL Expression from a string. I created a type StringLiteralExp and in the 
stringSymbol attribute  i give it the OCL string.

var strExp:=object 
OCL::expressions::StringLiteralExp{stringSymbol:='self.name=Class1'};
	
now i want to use this OCLExpression inside an if condition to evaluate it 
and check if it is true or false. However, it seems that the if condidtion 
always returns false. Which I guess because it is not correctly evaluating 
the ocl expression.

if(strExp=true) then 'true'.dump() else 'false'.dump() endif;

So my questions are : 1. Am-I using the correct way to build an OCL 
Expression from a string?

2. Is it possible to use the OCL expression inside an IF statement and to 
evaluate it ?

Thanks in advance..
