Class CompoundPropertyModel<T>

java.lang.Object
  org.apache.wicket.model.ChainingModel<T>
      org.apache.wicket.model.CompoundPropertyModel<T>

Type Parameters:

T - The model object type

All Implemented Interfaces:

Serializable, IChainingModel<T>, IComponentInheritedModel<T>, IDetachable, IModel<T>, IClusterable

public class CompoundPropertyModel<T>
extends ChainingModel<T>
implements IComponentInheritedModel<T>

A simple compound model which uses the component's name as the property expression to retrieve properties on the nested model object. CompoundPropertyModel is a chaining model so it will call get/setobject on the given object if the object is an instanceof IModel itself.

bind

public <S> IModel<S> bind(String property)

Binds this model to a special property by returning a model that has this compound model as its nested/wrapped model and the property which should be evaluated. This can be used if the id of the Component isn't a valid property for the data object.

Type Parameters:

S - the type of the property

Parameters:

property - the name that will be used to find

Returns:

The IModel that is a wrapper around the current model and the property

of

public static <Z> CompoundPropertyModel<Z> of(IModel<Z> model)

Type-infering factory method

Type Parameters:

Z - the type of the model's object

Parameters:

model - model

Returns:

CompoundPropertyModel instance
