Class ArrayUjoExt<UJO extends ArrayUjoExt>

java.lang.Object
  org.ujoframework.extensions.AbstractUjo
      org.ujoframework.extensions.AbstractUjoExt<UJO>
          org.ujoframework.implementation.array.ArrayUjoExt<UJO>

All Implemented Interfaces:

java.io.Serializable, UjoCloneable, UjoExt<UJO>, UjoMiddle<UJO>, UjoTextable, Ujo

public abstract class ArrayUjoExt<UJO extends ArrayUjoExt>
extends AbstractUjoExt<UJO>
implements java.io.Serializable

This is an Groovy style implementation of a setter and getter methods for an easier access for developpers, however the methods have got an weaker type control in compare to the MapUjo implementation.
Sample of usage:

public class Person extends ArrayUjoExt<Person> {

  public static final UjoProperty<Person, String > NAME = newProperty("Name" , String.class, propertyCount++);
  public static final UjoProperty<Person, Double > CASH = newProperty("Cash" , Double.class, propertyCount++);
  public static final UjoProperty<Person, Person> CHILD = newProperty("Child", Person.class, propertyCount++);
    
  public void init() {
    set(NAME, "George");
    set(CHILD, new Person());
    set(CHILD, NAME, "Jane");
    set(CHILD, CASH, 200d);
        
    String name = get(CHILD, NAME);
    double cash = get(CHILD, CASH);
  }
}

Method Summary

protected java.lang.Object[]	initData() The method is called from top constructor.
protected static <UJO extends ArrayUjoExt,ITEM> ListProperty<UJO,ITEM>	newListProperty(java.lang.String name, java.lang.Class<ITEM> type, int index) A ListProperty Factory Method assigns a next property index.
static <UJO extends ArrayUjoExt,VALUE> Property<UJO,VALUE>	newProperty(java.lang.String name, java.lang.Class<VALUE> type, int index) Returns a new instance of property where the default value is null.
protected static <UJO extends ArrayUjoExt,VALUE> Property<UJO,VALUE>	newProperty(java.lang.String name, VALUE value, int index) A Property Factory Method 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 Property.getValue(org.ujoframework.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 Property.setValue(org.ujoframework.Ujo, java.lang.Object) to an external access for a better type safe.

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(org.ujoframework.Ujo, java.lang.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.

Specified by:

writeValue in interface Ujo

Parameters:

property - Property must be a direct type only!

See Also:

Property.setValue(org.ujoframework.Ujo, java.lang.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(org.ujoframework.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.

Specified by:

readValue in interface Ujo

Parameters:

property - Property must be a direct type only!

Returns:

Property value

                                                                              int index)

Returns a new instance of property where the default value is null. Method assigns a next property index.
