Class ArrayUjo

java.lang.Object
  org.ujoframework.extensions.AbstractUjo
      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 ArrayUjoProperty" 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 ArrayProperty <Person,String > NAME  = newProperty("name" , String.class , propertyCount++);
    public static final ArrayProperty <Person,Boolean> MALE  = newProperty("male" , Boolean.class, propertyCount++);
    public static final ArrayProperty <Person,Date   > BIRTH = newProperty("birth", Date.class   , propertyCount++);

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

Method Summary

protected java.lang.Object[]	initData() The method is called from top constructor.
protected static <UJO extends Ujo,VALUE> ArrayProperty<UJO,VALUE>	newProperty(java.lang.String name, java.lang.Class<VALUE> type, int index) A Property Factory creates new property and assigns a next property index.
protected static <UJO extends Ujo,VALUE> ArrayProperty<UJO,VALUE>	newProperty(java.lang.String name, VALUE value, int index) A Property Factory creates new property and assigns a next property index.
protected static <UJO extends Ujo,ITEM> ArrayPropertyList<UJO,ITEM>	newPropertyList(java.lang.String name, java.lang.Class<ITEM> type, int index) A Property Factory creates new property and assigns a next property index.
abstract int	readPropertyCount() Return a count of properties.
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 ArrayProperty.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 ArrayProperty.setValue(Ujo,Object) to an external access for a better type safe.

Field Detail

propertyCount

protected static final int 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 ArrayProperty.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:

AbstractProperty.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 ArrayProperty.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
