org.metacosm.util
Class Property  

java.lang.Object
  org.metacosm.util.Property

All Implemented Interfaces:

java.lang.Cloneable, org.metacosm.framework.persistence.Persistent, java.io.Serializable

Direct Known Subclasses:

DoubleProperty, LongProperty, NonNumericProperty

---

public abstract class Property

extends java.lang.Object

implements java.lang.Cloneable, org.metacosm.framework.persistence.Persistent

Properties describe a particular aspect of an Entity. A Property is defined by a name and a value, which can be limited to some field. There are two main types of Properties: numeric ones and non-numeric ones.
Note: we haven't found some useful example where a 'null' value could be useful, so 'null' value is tested against.

clone

public java.lang.Object clone()

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }
