Interface BeanContentValidator<A>

Type Parameters:

A - The type of the beans to be validated by the validator interface.

public interface BeanContentValidator<A>

An utility interface to allow content validation on objects.

You can define content validators by extending this interface.

Imagine you have the following java bean class defined as:

 public class Person {
    private String name;
    private int age;
    
    public String getName(){return name;}
    public void setName(String name){this.name = name;}
    public int getAge(){return age;}
    public void setAge(int age){this.age = age;}
 }
 

You can define the following interface to check if objects have all of its properties filled or if them are all empty:

 public interface PersonValidator extends BeanContentValidator {}
 

To use the validator, just call GWT.create on the given interface, or inject it on your class.

 public class MyController {
    @Inject
    private PersonValidator validator;
    
    @Expose
    public void myMethod() {
       // read the object...
       if(!validator.isFilled(person)) {
           // ...
       }
    }
 }
