java.lang.Object
   com.sun.syndication.feed.impl.ObjectBean

ObjectBean
public class ObjectBean implements Serializable,Cloneable(Code)
Convenience class providing clone(), toString(), equals() and hashCode() functionality for Java Beans.

It works on all read/write properties, recursively.

It uses the CloneableBean, EqualsBean and ToStringBean classes in a delegation pattern.

ObjectBean programming conventions

All ObjectBean subclasses having properties that return collections they should never return null if the property has been set to null or if a collection has not been set. They should create and return an empty collection, this empty collection instance should also be set to the corresponding property.

All ObjectBean subclasses properties should be live references.

Constructor Summary
public  ObjectBean(Class beanClass, Object obj)
     Constructor.
public  ObjectBean(Class beanClass, Object obj, Set ignoreProperties)
     Constructor.

The property names in the ignoreProperties Set will not be copied into the cloned instance.


Method Summary
public  Objectclone()
     Creates a deep 'bean' clone of the object.
public  booleanequals(Object other)
     Indicates whether some other object is "equal to" this one as defined by the Object equals() method.


Parameters:
  other - he reference object with which to compare.

public  inthashCode()
     Returns a hashcode value for the object.
public  StringtoString()
     Returns the String representation for the object.


Constructor Detail
ObjectBean
public ObjectBean(Class beanClass, Object obj)(Code)
Constructor.


Parameters:
  beanClass - the class/interface to be used for property scanning.




ObjectBean
public ObjectBean(Class beanClass, Object obj, Set ignoreProperties)(Code)
Constructor.

The property names in the ignoreProperties Set will not be copied into the cloned instance. This is useful for cases where the Bean has convenience properties (properties that are actually references to other properties or properties of properties). For example SyndFeed and SyndEntry beans have convenience properties, publishedDate, author, copyright and categories all of them mapped to properties in the DC Module.


Parameters:
  beanClass - the class/interface to be used for property scanning.
Parameters:
  ignoreProperties - properties to ignore when cloning.





Method Detail
clone
public Object clone() throws CloneNotSupportedException(Code)
Creates a deep 'bean' clone of the object.

a clone of the object.
throws:
  CloneNotSupportedException - thrown if an element of the object cannot be cloned.




equals
public boolean equals(Object other)(Code)
Indicates whether some other object is "equal to" this one as defined by the Object equals() method.


Parameters:
  other - he reference object with which to compare. true if 'this' object is equal to the 'other' object.




hashCode
public int hashCode()(Code)
Returns a hashcode value for the object.

It follows the contract defined by the Object hashCode() method.

the hashcode of the bean object.




toString
public String toString()(Code)
Returns the String representation for the object.

String representation for the object.
