      • transformToPrimitiveConstantIfPossible

        public static ConstantExpression transformToPrimitiveConstantIfPossible​(ConstantExpression constantExpression)
        When constant expressions are created, the value is always wrapped to a non primitive type. Some constant expressions are optimized to return primitive types, but not all primitives are handled. This method guarantees to return a similar constant expression but with a primitive type instead of a boxed type. Additionaly, single char strings are converted to 'char' types.
        Parameters:
        constantExpression - a constant expression
        Returns:
        the same instance of constant expression if the type is already primitive, or a primitive constant if possible.
