Class CompoundPropertyModel<T>

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

Type Parameters:

T - The model object type

All Implemented Interfaces:

java.io.Serializable, IClusterable, IChainingModel<T>, IComponentInheritedModel<T>, IDetachable, IModel<T>

public class CompoundPropertyModel<T>
extends java.lang.Object
implements IComponentInheritedModel<T>, IChainingModel<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.

CompoundPropertyModel

public CompoundPropertyModel(IModel<T> model)

Constructor

Parameters:

model - The model

CompoundPropertyModel

public CompoundPropertyModel(T object)

Constructor

Parameters:

object - The model object

Method Detail

getObject

public T getObject()

Description copied from interface: IModel

Gets the model object.

Specified by:

getObject in interface IModel<T>

Returns:

The model object

See Also:

IModel.getObject()

setObject

public void setObject(T object)

Description copied from interface: IModel

Sets the model object.

Specified by:

setObject in interface IModel<T>

Parameters:

object - The model object

See Also:

IModel.setObject(java.lang.Object)

getChainedModel

public IModel<?> getChainedModel()

Description copied from interface: IChainingModel

Returns the chained model if there is a chained model.

Specified by:

getChainedModel in interface IChainingModel<T>

Returns:

The chained model

See Also:

IChainingModel.getChainedModel()

setChainedModel

public void setChainedModel(IModel<?> model)

Description copied from interface: IChainingModel

Sets the model that is chained inside this model.

Specified by:

setChainedModel in interface IChainingModel<T>

See Also:

IChainingModel.setChainedModel(org.apache.wicket.model.IModel)

detach

public void detach()

Description copied from interface: IDetachable

Detaches model after use. This is generally used to null out transient references that can be re-attached later.

Specified by:

detach in interface IDetachable

See Also:

IDetachable.detach()

propertyExpression

protected java.lang.String propertyExpression(Component component)

Returns the property expression that should be used against the target object

Parameters:

component -

Returns:

property expression that should be used against the target object

wrapOnInheritance

public <C> IWrapModel<C> wrapOnInheritance(Component component)

Specified by:

wrapOnInheritance in interface IComponentInheritedModel<T>

Type Parameters:

C - the model object type of the wrapped model

Returns:

The WrapModel that wraps this model

See Also:

IComponentInheritedModel.wrapOnInheritance(org.apache.wicket.Component)

bind

public <S> IModel<S> bind(java.lang.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 -

Returns:

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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

See Also:

Object.toString()

of

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

Type-infering factory method

Type Parameters:

Z -

Parameters:

model - model

Returns:

CompoundPropertyModel instance
