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

The return value is a collection of <a href="/Documentation:Tuple" title="Documentation:Tuple" data-bs-title="Documentation:Tuple">Tuple</a> containing the following:

1. Name
2. Description
3. IsDeleteConstraint: True/False
4. ErrorLevel: #Information, #Warning or #Error
5. Broken: Evaluated and <a href="/BestPractices:Subscribed" title="BestPractices:Subscribed" data-bs-title="BestPractices:Subscribed">Subscribed</a> state of the constraint

Examples

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

self.constraints->select(c|(c.ErrorLevel = #Error) and c.Broken)->isEmpty  -- Returns True if no errors

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 an array of booleans with the constraint result. To get the same functionality now, add .broken=false to the end of the previous expression.

Like this, used with <a href="/Documentation:OCLOperators_forAll" title="Documentation:OCLOperators forAll" data-bs-title="Documentation:OCLOperators_forAll">forAll</a>:

self.constraints->forAll(c|c.broken=false)
