How to get the particular static state(s) of a certain GameObject via script?

Hello everybody!

I'm writing the script for the Unity Editor. I want to know how to determine whether a certain GameObject instance has the particular static flag being set to true or false. I mean the following thing:

I know that the GameObject class has the property called "isStatic", but it returns true if there's at least one static flag from the whole flags list is set. However, I need to check only the particular flag (e.g., "Batching Static)" in my script.
