Class DatabaseFieldModel

java.lang.Object
  net.xoetrope.xui.data.XModel
      net.xoetrope.optional.data.sql.DatabaseFieldModel

public class DatabaseFieldModel
extends XModel

Provides a model for table field. The field will have no children. As a Java object the fields and rows indices are zero based in contrast to the JDBC indexing setup.

The class is not intended to be used directly except in rare circumstances, instead most access will be via the model and bindings or via the DatabaseTableModel class
