java.lang.Objectcom.sun.syndication.common.ObjectBean
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.
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.

protected ObjectBean(java.lang.Class beanClass)
beanClass
- the class/interface to be used for property scanning.protected ObjectBean(java.lang.Class beanClass, java.util.Set ignoreProperties)
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.
beanClass
- the class/interface to be used for property scanning.ignoreProperties
- properties to ignore when cloning.Method Detail |
public java.lang.Object clone() throws java.lang.CloneNotSupportedException
java.lang.CloneNotSupportedException
- thrown if an element of the object cannot be cloned.public boolean equals(java.lang.Object other)
other
- he reference object with which to compare.
public int hashCode()
It follows the contract defined by the Object hashCode() method.
public java.lang.String toString()
public java.lang.String toString(java.lang.String prefix)
This method is used by ToString implementations.
toString
in interface ToString
prefix
- prefix to use in the String representation.
