org.ujoframework.implementation.array
Class ArrayUjo

java.lang.Object
  extended by org.ujoframework.extensions.AbstractUjo
      extended by org.ujoframework.implementation.array.ArrayUjo
All Implemented Interfaces:
UjoCloneable, UjoTextable, Ujo
public abstract class ArrayUjo
extends AbstractUjo

This is a very fast abstract implementation of Ujo. For implementation define only a "public static final UjoProperty" constants and a "readPropertyCount()" method in a child class. The code syntax is Java 1.5 complied.
All properties must be objects (no primitive types) in the current version of UJO Framework.
Features: very good performance, an order of properties from "readProperties()" method is guaranteed and independed on a Java implementation.

Sample of usage

 import org.ujoframework.implementation.array.*;
 public class Person extends ArrayUjo {

    protected static int propertyCount = ArrayUjo.propertyCount;

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

    @Override
    public int readPropertyCount() {
        return propertyCount;
    }
 }

Field Detail

propertyCount

protected static final int propertyCount
An Incrementator. Use a new counter for each subclass by sample: 
 /** An Incrementator. Use a new counter for each subclass. */
 protected static int propertyCount = [SuperClass].propertyCount;

Method Detail

initData

protected java.lang.Object[] initData()
The method is called from top constructor.

readPropertyCount

public abstract int readPropertyCount()
Return a count of properties.

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 method can throws an ArrayIndexOutOfBoundsException.

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 can throws an ArrayIndexOutOfBoundsException.

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