Class BackupTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

views.BackupTableModel

All Implemented Interfaces:

java.io.Serializable, java.util.EventListener, javax.swing.event.TableModelListener, javax.swing.table.TableModel, BackupViewer

 class BackupTableModel
extends javax.swing.table.AbstractTableModel
implements javax.swing.event.TableModelListener, BackupViewer

This class extends the AbstractTableModel, which implements most of the methods required by TableModel interface and serves as a base class to implement customized tables.

This class also implements the BackupViewer interface to receive updates from the BackupManager and the TableModelListener interface, which defines the tableChanged(TableModelEvent e) method that is executed every time the table model changes.

Constructor Detail

BackupTableModel

BackupTableModel(BackupManager manager)

Class constructor. Registers the passed in BackupManager , updates itself and registers itself to listen for TableModelEvent events.

Parameters:

manager - instance of BackupManager that is shared between the model and the MainWindow

Method Detail

addRow

public void addRow(boolean selected,
          java.lang.String name,
          java.lang.String original,
          java.lang.String backup,
          boolean shallow,
          java.util.Date date)

This method is used to add new items into the table.

Parameters:

selected - defines whether the item is selected

name - value of the Name column

original - value of the Original Directory column

backup - value of the backup Directory column

shallow - defines whether the backup is defined as shallow

date - value of the Last Synchronized column

getBackupManager

public BackupManager getBackupManager()

Returns the associated BackupManager instance.

Returns:

returned BackupManager instance.

setBackupManager

public void setBackupManager(BackupManager mBackupManager)

Associates a BackupManager instance with this BackupTableModel.

getSelectedBackups

public java.util.Set<java.lang.String> getSelectedBackups()

Returns a Set of names of the selected backups.

Returns:

a Set of names of the selected backups

removeFromSelectedBackups

public void removeFromSelectedBackups(java.lang.String name)

Marks a backup with this name as not selected.

Parameters:

name - name of the backup

update

public void update()

Rebuilds this BackupTableModel.

clear

public void clear()

Clears this BackupTableModel.

getRowCount

public int getRowCount()

Returns the number of rows in the model. A JTable uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.

Specified by:

getRowCount in interface javax.swing.table.TableModel

Returns:

the number of rows in the model

See Also:

getColumnCount()

getColumnCount

public int getColumnCount()

Returns the number of columns in the model. A JTable uses this method to determine how many columns it should create and display by default.

Specified by:

getColumnCount in interface javax.swing.table.TableModel

Returns:

the number of columns in the model

See Also:

getRowCount()

getColumnName

public java.lang.String getColumnName(int column)

Returns a default name for the column using spreadsheet conventions: A, B, C, ... Z, AA, AB, etc. If column cannot be found, returns an empty string.

Specified by:

getColumnName in interface javax.swing.table.TableModel

Overrides:

getColumnName in class javax.swing.table.AbstractTableModel

Parameters:

column - the column being queried

Returns:

a string containing the default name of column

getColumnClass

public java.lang.Class<?> getColumnClass(int columnIndex)

Returns Object.class regardless of columnIndex.

Specified by:

getColumnClass in interface javax.swing.table.TableModel

Overrides:

getColumnClass in class javax.swing.table.AbstractTableModel

Specified by:

tableChanged in interface javax.swing.event.TableModelListener

Parameters:

e - instance of TableModelEvent

showBackupInfo
