class Container {
static hasMany = [children: Child]
}instanceOf
Purpose

Examples
Given the domain classes:
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
}
}Description
Parameters:
-
clazz- the type to check
