The Grails Framework 3.2.4

(Quick Reference) ## instanceOf ### Purpose Determines if a domain class instance is an instance of the specified class, resolving the actual class if the instance is a proxy. ### Examples Given the domain classes:
    class Container {
       static hasMany = [children: Child]
    }
    class Child {
       String name
       static belongsTo = [container: Container]
    }
    class Thing extends Child {}
    class Other extends Child {}
Then you can determine the type of the elements in a `Container’s `children` collection using
    def container = Container.get(id)
    for (child in container.children) {
       if (child.instanceOf(Thing)) {
          // process Thing
       }
       else if (child.instanceOf(Other)) {
          // process Other
       }
       else {
          // handle unexpected type
       }
    }
