The equalsSet operator returns true if the set on the left side contains all the elements in the set on the right-hand side. The two sides also must be equal in size.

For example, the following rule checks if you can find all the elements of the stock symbol set in the comma delimited string list (the right operand):

WHEN 3 stock s WITH s.symbol  equalsSet "XYZ, ABCD, EFG" then response

The following rule checks if you can find all of the elements of the stock symbol set in the comma delimited string list (the left operand):

WHEN 3 stock s WITH "XYZ, ABCD, EFG"  equalsSet s.symbol then response

The following rule checks whether all of the elements in the p.first_name set contains all of the items in the list returned by the SQL analytic:

WHEN 2 person p WITH p.first_name  equalsSet getPersonSql("EmployeeList") then response

The equalsSet operator returns true if the size of the list returned by the SQL analytic is equal to

p.first_name set size (size=2)

, and if the set and list contain the same elements.

The equalsSet operator is similar to the contains operator except that you can place a comma delimited string list on the right-hand side.
