org.ujoframework.implementation.map
Class MapUjo

java.lang.Object
  org.ujoframework.extensions.AbstractUjo
      org.ujoframework.implementation.map.MapUjo

All Implemented Interfaces:

java.io.Serializable, UjoCloneable, UjoTextable, Ujo

Direct Known Subclasses:

RegistrarUjo

public abstract class MapUjo
extends AbstractUjo
implements java.io.Serializable

This is a simple abstract implementation of Ujo.
Child implementation can use "public static final UjoProperty" constants for its UjoProperties. The code syntax is Java 1.5 complied.

Features: very simple implementaton and a sufficient performance for common tasks. The architecture is useful for a rare assignment of values in object too.

Sample of usage

 import org.ujoframework.implementation.map.*;
 public class Person extends MapUjo {

    public static final UjoProperty<Person,String > NAME  = newProperty("name" , String.class);
    public static final UjoProperty<Person,Boolean> MALE  = newProperty("male" , Boolean.class);
    public static final UjoProperty<Person,Date   > BIRTH = newProperty("birth", Date.class);

 }

Method Summary

protected static <UJO extends MapUjo,ITEM> ListProperty<UJO,ITEM>	newListProperty(java.lang.String name, java.lang.Class<ITEM> type) A ListProperty Factory Method assigns a next property index.
static <UJO extends MapUjo,VALUE> Property<UJO,VALUE>	newProperty(java.lang.String name, java.lang.Class<VALUE> type) Returns a new instance of property where the default value is null.
protected static <UJO extends MapUjo,VALUE> Property<UJO,VALUE>	newProperty(java.lang.String name, VALUE value) A Property Factory Method assigns a next property index.
static <UJO extends MapUjo,VALUE> Property<UJO,VALUE>	newProperty(UjoProperty p, int index) Returns a new instance of property where the default value is null.
protected static <UJO extends MapUjo,ITEM> ListProperty<UJO,ITEM>	newPropertyList(java.lang.String name, java.lang.Class<ITEM> type) Deprecated. Use newListProperty(...) instead of.
java.lang.Object	readValue(UjoProperty property) It is a common method for reading all object values, however there is strongly recomended to use a method Property.getValue(org.ujoframework.Ujo) to an external access for a better type safe.
void	writeValue(UjoProperty property, java.lang.Object value) It is a common method for writing all object values, however there is strongly recomended to use a method Property.setValue(org.ujoframework.Ujo, java.lang.Object) to an external access for a better type safe.

Method Detail

writeValue

public void writeValue(UjoProperty property,
                       java.lang.Object value)

It is a common method for writing all object values, however there is strongly recomended to use a method Property.setValue(org.ujoframework.Ujo, java.lang.Object) to an external access for a better type safe. The method have got a strategy place for an implementation of several listeners and validators.
NOTE: If property is an incorrect then no exception is throwed.

Specified by:

writeValue in interface Ujo

Parameters:

property - Property must be a direct type only!

See Also:

Property.setValue(Ujo,Object)

readValue

public java.lang.Object readValue(UjoProperty property)

It is a common method for reading all object values, however there is strongly recomended to use a method Property.getValue(org.ujoframework.Ujo) to an external access for a better type safe. The method have got a strategy place for an implementation of several listeners and convertors.
NOTE: If property is an incorrect then method returns a null value.

Specified by:

readValue in interface Ujo

Parameters:

property - Property must be a direct type only!

Returns:

Property value

Property.getValue(Ujo)

newProperty

Returns a new instance of property where the default value is null. Method assigns a next property index.

newProperty

protected static <UJO extends MapUjo,VALUE> Property<UJO,VALUE> newProperty(java.lang.String name,
                                                                            VALUE value)

A Property Factory Method assigns a next property index.

newProperty

public static <UJO extends MapUjo,VALUE> Property<UJO,VALUE> newProperty(UjoProperty p,
                                                                         int index)

Returns a new instance of property where the default value is null.

newListProperty

protected static <UJO extends MapUjo,ITEM> ListProperty<UJO,ITEM> newListProperty(java.lang.String name,
                                                                                  java.lang.Class<ITEM> type)

A ListProperty Factory Method assigns a next property index.

newPropertyList

protected static final <UJO extends MapUjo,ITEM> ListProperty<UJO,ITEM> newPropertyList(java.lang.String name,
                                                                                        java.lang.Class<ITEM> type)

Deprecated. Use newListProperty(...) instead of.
