Class BeanUjo

java.lang.Object
  org.ujoframework.extensions.AbstractUjo
      org.ujoframework.implementation.bean.BeanUjo

All Implemented Interfaces:

UjoCloneable, UjoTextable, Ujo

public abstract class BeanUjo
extends AbstractUjo

This abstract class is inteded for an easy implementation of UJO features to a completed JavaBean object.
A "name" of a BeanProperty is a JavaBean property name. By the "name" is deduced a setter and getter method name. The code syntax is Java 1.5 complied.

Features: an easy support of BEAN objects and the smallest memory footprint per one object.

Sample of usage

 import org.ujoframework.implementation.BEAN.*;
 public class Person extends BeanUjo {

    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);

    // ---- A STANDARD BEAN IMPLEMENTATION ----

    private String  name;
    private Boolean male;
    private Integer age ;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Boolean getMale() {
        return male;
    }
    public void setMale(Boolean male) {
        this.male = male;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
 }

Method Summary

protected static <UJO extends Ujo,ITEM> BeanPropertyList<UJO,ITEM>	newListProperty(java.lang.String name, java.lang.Class<ITEM> type) A ListProperty Factory for a BeanUjo object.
protected static <UJO extends Ujo,VALUE> BeanProperty<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 Ujo,VALUE> BeanProperty<UJO,VALUE>	newProperty(java.lang.String name, VALUE value) A Property Factory, a property type is related from the default value.
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 BeanProperty.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 BeanProperty.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 BeanProperty.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 method throws an IllegalArgumentException.

Parameters:

property - Property must be a direct type only!

See Also:

BeanProperty.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 BeanProperty.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 throws an IllegalArgumentException.

Parameters:

property - Property must be a direct type only!

Returns:

Property value

newProperty

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

A Property Factory, a property type is related from the default value. Method assigns a next property index.

newListProperty

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

A ListProperty Factory for a BeanUjo object. Method assigns a next property index.
