Question: Reusing Expression vs creating new one (Timer Calculation)

[ayman-metwally-developer]

Greetings,

I'm asking about the proper use from the designer point of view .. I'm evaluating hundreds of formulas per second .. it it normal to re-instantiate an object (New Expression) so frequently?

Regards,
Ayman

Hi Ayman,

sure, why not?

If you're evaluating the same formula all over again with different parameters,
just avoid parsing and reuse a parsed parameterized expression.

Years later to the party, but I think it's a valid point. Maybe a Object Pool solves this problem, but for this, Expression would need a Reset method or something to clear all the state, I don't know if it's worth.
