Class BinderModelBuilder<S,T>

java.lang.Object

org.nuiton.util.beans.BinderModelBuilder<S,T>

public class BinderModelBuilder<S,T>
extends Object

Class to create a new Binder.BinderModel.

A such object is designed to build only one model of binder and can not be used directly to create a new binder, it prepares only the model of a new binder, which after must be registred in the BinderFactory to obtain a real Binder.

If you want to create more than one binder model, use each time a new binder builder.

To obtain a new instance of a build please use one of the factories method :

• newEmptyBuilder(Class)} to create a binder model with same source and target type
• newEmptyBuilder(Class, Class) to create a binder model with a possible different source and target type
• newDefaultBuilder(Class) to create a binder model with same source and target type and then fill the model with all matching properties.
• newDefaultBuilder(Class, Class) to create a binder model with a possible different source and target type and then fill the model with all matching properties.

Then you can use folowing methods to specify what to put in the copy model :

• addSimpleProperties(String...) to add in the binder model simple properties (a simple property is a property present in both source and target type)
• addProperty(String, String) to add in the binder model a single property (from source type) to be copied to another property (in target type)
• addProperties(String...) to add in the binder model properties (says here you specify some couple of properties (sourcePropertyName, targetPropertyName) to be added in the binder model)
• addBinder(String, Binder) to add in the binder model another binder to be used to copy the given simple property (same name in source and target type)
• addCollectionStrategy(Binder.CollectionStrategy, String...) to specify the strategy to be used to bind some collection some source type to target type

Note : You can chain thoses methods since all of them always return the current instance of the builder :

 builder.addSimpleProperties(...).addProperty(...).addBinder(...)
 

Here is an example of how to use the BinderModelBuilder :

 BinderModelBuilder builder = new BinderModelBuilder(Bean.class);
 builder.addSimpleProperties("name", "surname");
 BinderFactory.registerBinderModel(builder);
 Binder binder = BinderFactory.getBinder(BeanA.class);

 

Once the binder is registred into the BinderFactory, you can get it each time you need it :

 Binder binder = BinderFactory.getBinder(Bean.class);
