I'm trying to create a method inside a class that will take Class
as a parameter and will check if the current object is of that type. The code i have:
public class MyEvent extends MyBPMNNode {
public boolean isKindOf(Class<?> node) {
boolean b = MyEvent.this instanceof node;
return b;
}
But i compile it it gives me:
Error:(9, 45) java: cannot find symbol
symbol: class node
What am i doing wrong here? Maybe my understanding of the ' Class
' class is not right.
You want:
public boolean isKindOf(Class<?> clazz) {
return clazz.isInstance(this);
}
您可能在node.isAssignableFrom(MyEvent.this)
。
You are introducing generics for no particular reason. Try this:
public boolean isKindOf(Object node) {
// weak
return node.getClass().isAssignableFrom(getClass());
// stronger, but not appropriate in your case
//return this.getClass().equals(node.getClass());
}
Andy Turner's answer is much more concise. Pardon me.
