booleanSetEquals Function Description
Description
This method returns true if both sets of attribute values of type boolean are equal. Technically, it uses the subset function on the first and second arguments ANDed with the subset function and the second and first argument. Note that duplicate values have no impact on the comparison. For instance, the following 2 sets are equal: [a,a,c,b] and [b,c,a,c].
booleanSetEquals belongs to the ALFA function reference's
Set functions category. It maps to the XACML function identifier
urn:oasis:names:tc:xacml:1.0:function:boolean-set-equals, takes 2 arguments and returns a value of type boolean.

* Using SetEquals on boolean makes little sense... But this is what it would look like.

rule booleanSetEqualsExample{

condition booleanSetEquals(securityChecksCleared, approvalsObtained)
}Using booleanSetEquals on booleans doesn't make much sense given there are only 2 possible values (true and false) and that there are much better ways to check for boolean values. Besides, how often is a value both true and false? That's exactly what Schrödinger's 🐈⬛ is wondering. Just try to think outside the 📦.
