org.ujoframework.implementation.map
Class MapUjo

java.lang.Object
  extended by org.ujoframework.extensions.AbstractUjo
      extended by org.ujoframework.implementation.map.MapUjo
All Implemented Interfaces:
UjoCloneable, UjoTextable, Ujo
Direct Known Subclasses:
RegistrarUjo
public abstract class MapUjo
extends AbstractUjo

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 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(Ujo,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.

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(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.

Parameters:
property - Property must be a direct type only!
Returns:
Property value
See Also:
Property.getValue(Ujo)

newProperty

public 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. 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.

                                                                                        java.lang.Class<ITEM> type)
Deprecated. Use newListProperty(...) instead of.
