Class MapUjo

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

All Implemented Interfaces:

UjoCloneable, UjoTextable, Ujo

Direct Known Subclasses:

RegistrarUjo

public abstract class MapUjo
extends SuperUjo

This is a simple abstract implementation of Ujo.
For implementation define only a "public static final MapProperty" constants in a child class. 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 MapProperty <Person,String > NAME  = newProperty("name" , String.class);
    public static final MapProperty <Person,Boolean> MALE  = newProperty("male" , Boolean.class);
    public static final MapProperty <Person,Date   > BIRTH = newProperty("birth", Date.class);

 }

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 MapProperty.getValue(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 MapProperty.setValue(Ujo,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 MapProperty.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:

SuperProperty.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 MapProperty.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
