Get all operator from a parameter

minet.axel — Fri, 05 Feb 2021 14:43:00 GMT

Good morning all,

I am looking for a way to get all the operators for a given parameter. Do you have any idea, I couldn't find anything in the API that allows me to do this.
The goal is to recover these values:

And create the right filter according to the user's choice :

"equals" :

ParameterFilterRuleFactory.CreateEqualsRule(

"is greater than or equal to" :

ParameterFilterRuleFactory.CreateGreaterOrEqualRule(

thk

Do I need to test the type of parameter and create the list against the type of parameter (storageType)?

Hey,

I think you are right. You could check the storage type. In that way, you will be able to know if a method is available to be used over a certain parameter or not. Once you validate the method, you get the operator.
