Interface IRowsDataObject

All Superinterfaces:

IBoundObject

All Known Implementing Classes:

DataSourceDataRows

public interface IRowsDataObject

extends IBoundObject

This interface represents an array (rows) of objects. Individual elements in the array can be accessed and modified by using the get() and set() methods. Interested parties can register as a RowChangeListener to be notified when the contents of a particular row are changed. When all rows change, the RowChangeEvent will report ALL_ROWS as the changed index.

Nested Class Summary

static class	IRowsDataObject.RowChangeEvent A RowChangeEvent is fired when the contents of a row changes in the array maintained by the RowDataObject.
static interface	IRowsDataObject.RowChangeListener Interface used to register for row change notification.

Field Summary

static int	ALL_ROWS Row index used to indicate all rows changing in an RowChangeEvent
static int	DESIGNTIME_ROWS Number of example rows to generate in design time

Fields inherited from interface jve.generated.IBoundObject

DELIMITER, PROPERTY_OBJ_CHANGED

Method Summary

void	addRowChangeListener(IRowsDataObject.RowChangeListener l) Add a new row change listener to the listener list.
java.lang.Object	get(int index) Retrieve the value of the row at the given index.
int	getLength() Returns the number of rows in this array
void	removeRowChangeListener(IRowsDataObject.RowChangeListener l) Remove an existing row change listener from the listener list.
void	set(int index, java.lang.Object value) Set the value at the given index
