I'm currently experimenting with the idea of putting my domain object into
the prototype. Consider this:
// my java domain class
public class DomainEntity {
public void save() {
System.out.println("DomainEntity.save()");
}
public void delete() {
System.out.println("DomainEntity.delete()");
}
}
// my Java Host object wrapper
public class HostEntity extends ScriptableObject {
public HostEntity() {
super();
DomainEntity proto = new DomainEntity();
NativeJavaObject jsproto = new NativeJavaObject(scope, proto, null);
setPrototype(jsproto);
}
public void jsFunction_save() {
System.out.println("HostEntity.save()");
}
}
The idea is that methods found in HostEntity will be executed before those
found in DomainEntity.
So this JS code:
var obj = new HostEntity();
obj.save();
obj.delete();
will produce this output:
HostEntity.save()
DomainEntity.delete()
The obvious problem is that "scope" is not available at this line:
NativeJavaObject jsproto = new NativeJavaObject(scope, proto, null);
I don't see any way of getting the "current scope" as one might get the
current context. Am on the right track with what I want to accomplish or is
there a better way. I'm open to hearing how anyone else handles an "API"
layer between their Java domain classes and what is exposed to Javascript.
Thanks.
