Class Fragment

java.lang.Object

org.nuxeo.ecm.core.storage.sql.Fragment

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

CollectionFragment, SimpleFragment

public abstract class Fragment
extends Object
implements Serializable

A rich value corresponding to one row or a collection of rows in a table.

In addition to the basic Row, this holds the old values (to check dirty state), the state and a reference to the session.

This class has two kinds of state-changing methods:

• the "set" ones, which only change the state,
• the "mark" ones, which change the state and do the corresponding changes in the pristine/modified maps of the context.
