Evaluators

Evaluators are used to define conditions that determine whether a block of configuration should be included in the evaluated and merged configuration document.

Evaluators work on different aspects of the runtime experience, including:

  • what is being observed
  • who is observed it
  • what URL is being looked at
  • what objects are known about at the time (i.e. observables)
  • what permissions and authorities the current user has over things that are being observed

There are many types of evaluators available.

Boolean evaluators assumed a condition of true which tests for the evaluator to return true. You can adjust this to test the opposite by setting condition to false.
