public void update(java.util.Observable dispModel,
                   java.lang.Object arg1)

The model would call this method when its state has change.

Specified by:

update in interface java.util.Observer

See Also:

Observer.update(java.util.Observable, java.lang.Object)

getPortaViewModel

public PortaViewModel getPortaViewModel()

Returns:

the PortaViewModel associated with this view.

setPortaViewModel

public void setPortaViewModel(PortaViewModel model)

Sets the PortaViewModel

Parameters:
