Entry

java.lang.Object
- com.google.gdata.model.Element
- - com.google.gdata.model.atom.Entry

All Implemented Interfaces:

IAtom, IEntry

Direct Known Subclasses:

EventEntry, MessageEntry, RecurrenceExceptionEntry
```
public class Entry
extends Element
implements IEntry
```
The Entry class is a base class that defines the in-memory object model for GData entries.
Entry subclasses should expose convenience APIs to retrieve and set attributes or subelements, with implementations that delegate to Element methods to store/retrieve the appropriate data.
Here is the Relax-NG schema that represents an Atom 1.0 entry:
```
 atomEntry =
   element atom:entry {
     atomCommonAttributes,
     (atomAuthor*
     & atomCategory*
     & atomContent?
     & atomContributor*
     & atomId
     & atomLink*
     & atomPublished?
     & atomRights?
     & atomSource?
     & atomSummary?
     & atomTitle
     & atomUpdated
     & extensionElement*)
 
```
