org.dspace.app.xmlui.utils.DSpaceValidity
This is a validity object specifically implemented for the caching needs of DSpace, Manakin, and Cocoon. The basic idea is that each time a DSpace object rendered by a cocoon component the object and everything about it that makes it unique should be reflected in the validity object for the component. By following this principle if the object has been updated externally then the cache will be invalidated. This DSpaceValidity object makes this processes easier by abstracting out the processes of determining what is unique about a DSpace object. A class is expected to create a new DSpaceValidity object and add() to it all DSpaceObjects that are rendered by the component. This validity object will serialize all those objects to a string, take a hash of the string and compare the hash of the string for any updates. @author Scott Phillips
