Constructor Detail

HostViewModel

public HostViewModel(PropertyInitializer prop_init)

This will be a constructor that can be called if there is no preexisting data model. It will create a data model.

HostViewModel

public HostViewModel()

HostViewModel

private HostViewModel(HostDataModel model)

Method Detail

initialize

public void initialize(HostDataModel model)

Initialize is called when a view model object is created on a data model object. It does a lot of the functionality that used to be in the constructor but that had to be moved.

Parameters:

model -

reinitialize

public void reinitialize()

Reinitialize all sub-components and connections. Add yourself as a listener to your data model.

Overrides:

reinitialize in class AbstractNodeViewModel

See Also:

AbstractDESIModel.reinitialize()

setMyXADLModel

public void setMyXADLModel(HostDataModel myXADLModel)

Set this property with a xADL model if you are running on top of a xADL file.

Parameters:

myXADLModel - The myXADLModel to set.

getMyXADLModel

public HostDataModel getMyXADLModel()

Returns:

Returns the myXADLModel.

finalize

public void finalize()
              throws java.lang.Throwable

Just to make sure that nothing keeps this class as a listener after the object has been eliminated.

Throws:

java.lang.Throwable

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

On propertyChange, this class will respond to any additions or subtractions of components or connections by the HostDataModel. It will then report the change to all listeners.

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

Overrides:

propertyChange in class AbstractDESIModel

private void privateAddConnection(PhysicalLinkViewModel link)

Adds a link to this host if the link is not already added.

Parameters:

link - PhysicalLinkViewModel

addConnection

public void addConnection(PhysicalLinkViewModel link)

This is the public version of addConnection and it will add a physical link to this host when the host is connected.

Parameters:

link -

privateRemoveConnection

private void privateRemoveConnection(PhysicalLinkViewModel link)

Removes the link from the host. If link is not in host, nothing happens.

Parameters:

link - PhysicalLinkViewModel

removeConnection

public void removeConnection(PhysicalLinkViewModel link)

This is teh public version of remove connection and it will remove a physical link from connecting this host.

Parameters:

link -

setPropertyValue

public void setPropertyValue(java.lang.String prop_name,
                             java.lang.Object value)

                             java.lang.ClassCastException

I overrode this method:

Overrides:

AbstractViewModel.setPropertyValue(java.lang.String, java.lang.Object)

layoutComponents

public void layoutComponents()

Call this method and all the children will be put in their proper place in the layout. It does so by clearing the bit set and then assigning every component a new position.

colorLinksRed

public void colorLinksRed()

When called, this method will change the color of all attached links to red.

colorLinksBlack

public void colorLinksBlack()

When called, this method will change the color of all attached links to black.
