newInstance

public <T extends Entity> T newInstance(TxBindings txBindings,

Description copied from interface: CustomEntityFactory

Construct a custom entity class that implements entityInterface replacing the default class.

The interface is self-implementing; default methods delegate to bindings. As a consequence, a custom entity class can focus on custom behavior and not be concerned about maintaining existing behavior.

A typical custom entity class.

     import org.example.schema.sampledb.Actor;
     import manifold.sql.rt.api.TxBindings;

     public class CustomActor implements Actor extends BaseEntity {
       private CustomActor(TxBindings bindings) {
         super(bindings);
       }

       // your code here...

     } 

A custom class may override any of the entityInterface methods and provide any number of its own methods.

Specified by:

newInstance in interface CustomEntityFactory

Type Parameters:

T - The entity interface to implement.

Parameters:

txBindings - The TxBindings instance the returned class instance receives in its constructor. This instance must be maintained by this class and returned from the getBindings() method.

entityInterface - The interface the class of the returned entity instance must implement.

Returns:

An instance of the entityInterface or null the entity is not customized.
