Is Meta good for performance?, GetMeta, SetMeta....

Hi guys, I hope you will give me urgent answer for my question, is meta good for performance?, Meta is amazing and great in different ways, it gives you abilities to extend or add features for your project without making a muss or changing your original project. I'm using it with few objects or nodes but now I need it with hundreds of objects or nodes, some times i need to call these objects many times and check their meta, the question is: Is meta good for performance or not? I use C#, so I need to do something like that many times on hundreds of nodes:

=============================

if(Node.HasMeta("Shield"))
	sheild=(bool)Node.GetMeta("Shield);

Thank you

Hi,

I am not 100% sure, but I guess that the most probably meta data for objects are stored in dictionary.

Looking at dictionary implementation it seems to be a hash map and you can even see comment:

A hash map which allows to iterate elements in insertion order. Insertion, lookup, deletion have O(1) complexity.

So it should be fast, but may use more memory.

Edit: I checked, metadata is Dictionary. That is in object.h:

(...)
	Dictionary metadata;
