Constructor Detail

TransactionalJDOTableModel

protected TransactionalJDOTableModel()

Default constructor. Cannot be directly instantiated.

TransactionalJDOTableModel

public TransactionalJDOTableModel(D model)

Create a new table model for objects of the specified type. Note that callers must invoke JDOTableModel.init() for table model to be initialised.

Parameters:

model - A dummy object used to initialise the table model. Note that the dummy object need not be a persistent instance.

See Also:

JDOTableModel.init()

Method Detail

addRow

public void addRow(D row)

Add the specified object to the end of the model. Over-ridden to persist the object to the data store. If persistence fails the object is not appended to the model.

Overrides:

addRow in class JDOTableModel<D>

Parameters:

row - The data object that is to be added to the model.

See Also:

save(D), TableModel.addRow(D)

insertRow

public void insertRow(int row,
                      D rowData)

Insert the specified object at the specified row index into the model. Over-ridden to persist the rowData object to the data store. If persisting the object fails the model is not updated.

Overrides:

insertRow in class JDOTableModel<D>

Parameters:

row - The index at which the object is to be inserted.

rowData - The object that is to be added to the model.

See Also:

save(D), TableModel.insertRow(int, D)

updateRow

public void updateRow(int row,
                      D rowData)

Replace the row specified with the object specified. Over-ridden to persist the object to the data store prior to delegating to super class implementation. If persisting the object fails, no update is performed on the table model.

Overrides:

updateRow in class TableModel<D>

Parameters:

row - The index at which the object is to be updated.

rowData - The new object that is to be used in the model.

See Also:

TableModel.updateRow(int, D)

deleteRow

public void deleteRow(int row)

Delete the specified row from the model. Over-ridden to delete the persistent instance from the data store. The table model is not modified if the data store could not be modified.

Overrides:

deleteRow in class JDOTableModel<D>

Parameters:

row - The index of the row that is to be deleted.

See Also:

delete(int), TableModel.deleteRow(int)
