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 } }
Description
Parameters:
clazz- the type to check
