Examples of org.geotools.data.store.ContentEntry

org.geotools.data.store.ContentEntry
An entry for a type or feature source provided by a datastore.
This class is only of concern to subclasses, client code should never see this class.

An entry maintains state on a per-transaction basis. The {@link #getState(Transaction)}method is used to get at this state.
```
  ContentEntry entry = ...; Transaction tx1 = new Transaction(); Transaction tx2 = new Transaction(); ContentState s1 = entry.getState( tx1 ); ContentState s2 = entry.getState( tx2 ); s1 != s2;  
```
