Class StaticAttribute<T,​R>

  • Type Parameters:
    T - the class of the item this attribute maps into.
    R - the class that the value of this attribute converts to.
    @ThreadSafe
public final class StaticAttribute<T,​R>
extends Object
    A class that represents an attribute that can be read from and written to an mapped item. A StaticTableSchema composes multiple attributes that map to a common item class.

    The recommended way to use this class is by calling StaticTableSchema.Builder.addAttribute(Class, Consumer). Example: 

    
 StaticTableSchema.builder()
                  .addAttribute(String.class,
                                a -> a.name("customer_name").getter(Customer::getName).setter(Customer::setName))
                  // ...
                  .build();

    It's also possible to construct this class on its own using the static builder. Example: 

    
 StaticAttribute<Customer, ?> customerNameAttribute =
     StaticAttribute.builder(Customer.class, String.class)
                    .name("customer_name")
                    .getter(Customer::getName)
                    .setter(Customer::setName)
                    .build();
