The operator return both meta information about a class's constraints and if it's currently broken.

The return value is a collection of Tuple containing the following

  1. Name
  2. Description
  3. IsDeleteConstraint: True/False
  4. ErrorLevel: #Information, #Warning or #Error
  5. Broken:Evaluated and Subscribed state of the constraint
Examples

To check if any constraint with error level Error is broken;

self.constraints->select(c|c.ErrorLevel = #Error)->forAll(c|c.Broken)

The same thing, differently expressed;

self.constraints->select(c|(c.ErrorLevel = #Error) and c.Broken)->notEmpty

Returning a collection of Descriptions of broken Warning constraints;

self.constraints->select(c|(c.ErrorLevel = #Warning) and c.Broken)->collect(c|c.Description)
Please note

This operator earlier resulted in a array of constraint names. To get the same functionality now, add .name to the end of the previous expression.
