Constructor Detail

JAPRoutingInfoServiceRegistrationTableModel

public JAPRoutingInfoServiceRegistrationTableModel()

Creates a new instance of JAPRoutingInfoServiceRegistrationTableModel. We do only some initialization here.

Method Detail

updatePropagandaInstancesList

public void updatePropagandaInstancesList(java.util.Vector a_newPropagandaInstancesList)

Updates the list of all displayed propaganda instances. We add only new unknown instances here, because removing of the old ones is done automatically, when they are stopped.

Parameters:

a_newPropagandaInstancesList - A Vector with propaganda instances. The new ones are added to the internal list.

update

public void update(java.util.Observable a_notifier,
                   java.lang.Object a_message)

This is the implementation of the observer of the propaganda instances. So if the instances change the state, the table is updated automatically. If the instances reach the state HALTED, they are removed from the table.

Specified by:

update in interface java.util.Observer

Parameters:

a_notifier - The propaganda instance, which has changed the state.

getRowCount

public int getRowCount()

Returns the number of rows in the infoservice registration table. This is equal to the number of propaganda instances.

Specified by:

getRowCount in interface javax.swing.table.TableModel

Returns:

The number of rows in the infoservice registration table.

getColumnCount

public int getColumnCount()

Returns the number of columns in the infoservice registration table. This is always 2, where column 0 is the name of the infoservice and column 2 is the connection state.

Specified by:

getColumnCount in interface javax.swing.table.TableModel

Returns:

The number of columns in the infoservice registration table.

getColumnName

public java.lang.String getColumnName(int a_column)

Returns the name of the specified column. The name is resolved via JAPMessages.

Specified by:

getColumnName in interface javax.swing.table.TableModel

Overrides:

getColumnName in class javax.swing.table.AbstractTableModel

Parameters:

a_column - The number of the column to get the name for. If this is not a valid column number, null is returned.

Returns:

The name for the column.

getValueAt

public java.lang.Object getValueAt(int a_row,
                                   int a_column)

Returns a value of a cell in the table. In column 0 always the names of the infoservices and in column 1 always the registration status appear. If the specified values for row or column are outside the borders of the table, null is returned.

Specified by:

getValueAt in interface javax.swing.table.TableModel

Parameters:

a_row - The row (propaganda instance) to get the value for.

a_column - The column to get the value for.

Returns:

A String with the value of the specified cell.

clearPropagandaInstancesTable

public void clearPropagandaInstancesTable()

Removes all propaganda instances from the table. Also observing of those propaganda instances is stopped.
