DatabaseFieldModel

public class FieldModel
extends DataModel

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 TableModel class

Method Summary

void	append(DataModel newObject) This method is required by the DataModel interface but in this case it is not implemented as it is inappropriate in the context of the class
java.lang.Object	append(java.lang.String id) This method does not nothing it is provided merely as an implementation of the DataModel interface.
java.lang.Object	get() Get the field value
DataModel	get(int i) Not yet implemented - does nothing
java.lang.String	getAttribName(int i) This method is required by the DataModel interface but in this case it is not implemented as it is inappropriate in the context of the class
