ExpressionConfiguration.StandardOperatorsDictionary not working

[FlorianPoessl]

I am using version 3.0.5 and I am trying to get all possible functions and operators because I need them for some internal checking.
The constant ExpressionConfiguration.StandardOperatorsDictionary as stated in the documentation does not exist.

I then tried using "ExpressionConfiguration.defaultConfiguration().getFunctionDictionary()" but I only got a FunctionDictionaryIfc.
I guess I want the MapBasedFunctionDictionary to iterate over all functions. How do i get the MapBasedFunctionDictionary? Am I doing something wrong?

Nevermind, a typecast did the job. For anyone else searcing for the solution, here is my code that worked:

MapBasedFunctionDictionary functions = (MapBasedFunctionDictionary) ExpressionConfiguration.builder().build().getFunctionDictionary()
