Interface WritableTableFormat<E>

All Superinterfaces:

TableFormat<E>

public interface WritableTableFormat<E>
extends TableFormat<E>

Specifies how to edit the elements of table.

This class can be used as an alternative to the simple TableFormat class to provide editable cells. The EventTableModel detects if a class implements WritableTableFormat for modifying the table. If a table is not editable at all, it is sufficient to implement TableFormat only.

Method Detail

isEditable

boolean isEditable(E baseObject,
                   int column)

For editing fields. This returns true if the specified Object in the specified column can be edited by the user.

Parameters:

baseObject - the Object to test as editable or not. This will be an element from the source list.

column - the column to test.

Returns:

true if the object and column are editable, false otherwise.

Since:

2004-August-27, as a replacement for isColumnEditable(int).

setColumnValue

E setColumnValue(E baseObject,
                 Object editedValue,
                 int column)

Sets the specified field of the base object to the edited value. When a column of a table is edited, this method is called so that the user can specify how to modify the base object for each column.

Parameters:

baseObject - the Object to be edited. This will be the original Object from the source list.

editedValue - the newly constructed value for the edited column

column - the column which has been edited

Returns:

the revised Object, or null if the revision shall be discarded. If not null, the EventTableModel will set() this revised value in the list and overwrite the previous value.
