Class Model<T extends java.io.Serializable>

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

Type Parameters:

T - The type of the Model Object

All Implemented Interfaces:

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

public class Model<T extends java.io.Serializable>
extends java.lang.Object
implements IModel<T>

Model is the basic implementation of an IModel. It just wraps a simple model object. The model object must be serializable, as it is stored in the session. If you have large objects to store, consider using LoadableDetachableModel instead of this class.

Constructor Detail

Model

public Model()

Construct the model without providing an object.

Model

public Model(T object)

Construct the model, setting the given object as the wrapped object.

Parameters:

object - The model object proper

Method Detail

valueOf

@Deprecated
public static <K,V> IModel<java.util.Map<K,V>> valueOf(java.util.Map<K,V> map)

Deprecated. see of(Map)

Type Parameters:

K - type of key inside map

V - type of value inside map

Parameters:

map - The Map, which may or may not be Serializable

Returns:

A Model object wrapping the Map

valueOf

@Deprecated
public static <C> IModel<java.util.List<? extends C>> valueOf(java.util.List<? extends C> list)

Deprecated. see of(List)

Type Parameters:

C - type of object inside list

Parameters:

list - The List, which may or may not be Serializable

Returns:

A Model object wrapping the List

of

public static <C> IModel<java.util.List<? extends C>> of(java.util.List<? extends C> list)

Factory method for models that contain lists. This factory method will automatically rebuild a nonserializable list into a serializable one.

Type Parameters:

C - model type

Parameters:

list - The List, which may or may not be Serializable

Returns:

A Model object wrapping the List

of

@Deprecated
public static <K,V> IModel<java.util.Map<K,V>> of(java.util.Map<K,V> map)

Deprecated. use ofMap(Map)

Factory method for models that contain maps. This factory method will automatically rebuild a nonserializable map into a serializable one.

Type Parameters:

K - key type in map

V - value type in map

Parameters:

map - The Map, which may or may not be Serializable

Returns:

A Model object wrapping the Map

ofMap

public static <K,V> IModel<java.util.Map<K,V>> ofMap(java.util.Map<K,V> map)

Factory method for models that contain maps. This factory method will automatically rebuild a nonserializable map into a serializable one.

Type Parameters:

K - key type in map

V - value type in map

Parameters:

map - The Map, which may or may not be Serializable

Returns:

A Model object wrapping the Map

of

public static <C> IModel<java.util.Set<? extends C>> of(java.util.Set<? extends C> set)

Factory method for models that contain sets. This factory method will automatically rebuild a nonserializable set into a serializable one.

Type Parameters:

C - model type

Parameters:

set - The Set, which may or may not be Serializable

Returns:

A Model object wrapping the Set

of

public static <C> IModel<java.util.Collection<? extends C>> of(java.util.Collection<? extends C> set)

Factory method for models that contain collections. This factory method will automatically rebuild a nonserializable collection into a serializable ArrayList.

Type Parameters:

C - model type

Parameters:

set - The Collection, which may or may not be Serializable

Returns:

A Model object wrapping the Set

of

public static <T extends java.io.Serializable> Model<T> of(T object)

Factory methods for Model which uses type inference to make code shorter. Eqivalent to new Model(object).

Type Parameters:

T -

Parameters:

object -

Returns:

Model that contains object

getObject

public T getObject()

Description copied from interface: IModel

Gets the model object.

Specified by:

getObject in interface IModel<T extends java.io.Serializable>

Returns:

The model object

See Also:

IModel.getObject()

setObject

public void setObject(T object)

Set the model object; calls setObject(java.io.Serializable). The model object must be serializable, as it is stored in the session
