Constructor Detail

JAPRoutingConnectionClassSelector

public JAPRoutingConnectionClassSelector()

This creates a new instance of JAPRoutingConnectionClassSelector. Also all connection classes are initialized here and the currently used connection class is set to a default value.

Method Detail

getCurrentConnectionClass

public JAPRoutingConnectionClass getCurrentConnectionClass()

This returns the currently used connection class.

Returns:

The currently used connection class.

setCurrentConnectionClass

public void setCurrentConnectionClass(int a_connectionClass)

This changes the currently used connection class. Also this methode must be called after a change of the parameters of the current connection class in order to update the forwarding system to the new bandwidth/user values. When the connection class has been changed, a CONNECTION_CLASS_CHANGED JAPRoutingMessage is sent to all observers of this class. Also a CONNECTION_PARAMETERS_CHANGED JAPRoutingMessage is sent, if the connection number/bandwidth parameters of the forwarding system has been changed.

Parameters:

a_connectionClass - The ID of the new connection class. If this is not a valid ID, nothing is done.

getConnectionClasses

public java.util.Vector getConnectionClasses()

Returns a Vector of all connection classes.

Returns:

The Vector with all connection classes.

getSettingsAsXml

public org.w3c.dom.Element getSettingsAsXml(org.w3c.dom.Document a_doc)

Returns the current connection class settings (currently selected connection class, settings of the single connection classes) for storage within an XML document.

Parameters:

a_doc - The context document for the connection class settings.

Returns:

An XML node (ConnectionClassSettings) with all connection class settings.

loadSettingsFromXml

public boolean loadSettingsFromXml(org.w3c.dom.Element a_connectionClassSettingsNode)

This method loads all connection classes related settings from a prior created XML structure. If there is an error while loading the settings, it is still tried to load as much settings as possible.

Parameters:

a_connectionClassSettingsNode - The ConnectionClasses XML node, which was created by the getSettingsAsXml() method.

Returns:

True, if there was no error while loading the settings and false, if there was one.
