Parameters:

Method Detail

initializeAlgos

private void initializeAlgos()

This method will initialize the algorithms that can be run. It will appropriately fill the myAlgosAndResults Hash.

createPartControl

public void createPartControl(org.eclipse.swt.widgets.Composite parent)

Description copied from class: AbstractPage

This method is overridden, to make each page special.

Specified by:

createPartControl in interface org.eclipse.ui.IWorkbenchPart

Specified by:

createPartControl in class AbstractPage

layoutView

private void layoutView(org.eclipse.swt.widgets.Composite parent)

This method will, once the main grid layout is setup, will add all the pieces of the view to it. This nees to be a method separate from createPartControl because sometimes, like on a model switch, we may just want to re-layout everything.

Parameters:

parent -

createAlgoSection

private void createAlgoSection(org.eclipse.swt.widgets.Composite parent)

createConstraintsSection

private void createConstraintsSection(org.eclipse.swt.widgets.Composite parent)

This method will create the constraints section. This includes all the widgets necessary for fixing a component to a host, preventing it and for collocating or prenting components from collocating. For the first time, this entire section ISN'T being taken from old DESI code, so I'm kinda winging it here.

Parameters:

parent -

createInputSection

private void createInputSection(org.eclipse.swt.widgets.Composite parent)

This method will create the input section, all the widgets needed for specifying and randomly generating new Systems and Deployments. Almost all of the widgets in this method, with the exception of the availability meter, do not need to be updated with the system. That's sort of the reason why everything's just plopped down in this one method. This method has now become extra special because the properties will be read from the dynamic property holder to create the widgets.

Parameters:

parent - Composite - The parent SWT widget of this section.

createResultsSection

private void createResultsSection(org.eclipse.swt.widgets.Composite parent)

This method creates the section of the tabular page where the results are displayed. Of course now the results aren't really displayed there but instead the selection widget which allows you to go back to all the old algorithm results.

Parameters:

parent - Composite - The parent SWT widget of this section.

createTabbedSection

private void createTabbedSection(org.eclipse.swt.widgets.Composite parent)

There is a section of the tabular view that contains tabbed pages that give the current status of the system. This private method will set up that entire section.

Parameters:

parent -

generate

private void generate()

This method is called when someone hits the generate button. It runs a new generator passing it the input data and property initer.

createCollocTable

private void createCollocTable(org.eclipse.swt.widgets.Composite parent)

This method will create the co-location table which will be presented in the the constraints section.

Parameters:

parent -

createLocTable

private void createLocTable(org.eclipse.swt.widgets.Composite parent)

This is the method that creates the location constraints table. It first creates its JFace TableViewer and then it has to set up the table by adding our custom label and content providers. This table will display location constraints for components and it will put them inside the parent SWT component.

Parameters:

parent -

createHostTable

private void createHostTable(org.eclipse.swt.widgets.Composite parent)

This method will create the Hosts Table. If it needs to be in a group or a tabbed group, this is determined by the Composite that is passed in. In this method, we create a Table and a JFace table on top. Then we give it the appropriate Content and Label providers so that the model and changes to it will be handled correctly.

Parameters:

parent - Composite - The parent SWT Widget of this table.

createDeploymentTable

private void createDeploymentTable(org.eclipse.swt.widgets.Composite parent)

Create a table of component deployments.

Parameters:

parent -

createLogicalLinkPropertyTable

private void createLogicalLinkPropertyTable(org.eclipse.swt.widgets.Composite parent,
                                            java.lang.String prop_name)

Create a table that will display the given property of logical links.

Parameters:

parent - Composite - The SWT parent widget of this table.

prop_name - String - The name of the property of logical links this table will display.

createPhysicalLinkPropertyTable

private void createPhysicalLinkPropertyTable(org.eclipse.swt.widgets.Composite parent,
                                             java.lang.String prop_name)

Create a table that will display the given property of physical links.

Parameters:

parent - Composite - The SWT parent widget of this table.

prop_name - String - The name of the property of Physical Links to display.

createHostBWTable

private void createHostBWTable(org.eclipse.swt.widgets.Composite parent)

This method creates the table that shows the bandwisth of the links between the hosts. It needs to be passed a parameter which will be the parent SWT widget of the table.

Parameters:

parent - Composite - The parent SWT widget of this table.

createComponentsTable

private void createComponentsTable(org.eclipse.swt.widgets.Composite parent)

This method creates a TableViewer for the components table and adds it to the given parent SWT Widget. The components table shows all the properties of a component.

Parameters:

parent - Composite - The parent SWT widget of this table.

createComponentsEvtSizeTable

private void createComponentsEvtSizeTable(org.eclipse.swt.widgets.Composite parent)

This method will create a TableViewer for the component table that shows component event sizes. It will add this table to the given parent widget.

Parameters:

parent - Composite - The parent SWT widget of this table.

getPageName

public java.lang.String getPageName()

Description copied from class: AbstractPage

What is the readable name of this page?

Specified by:

getPageName in class AbstractPage

Returns:

String

registerEditPartViewer

protected void registerEditPartViewer(org.eclipse.gef.EditPartViewer viewer)

Description copied from class: AbstractPage

If this page has an viewer, it must be registered with the Editor and the edit domain.

Specified by:

registerEditPartViewer in class AbstractPage

Parameters:

setFocus

public void setFocus()

Description copied from class: AbstractPage

Call set focus on our graphical viewer. (This really only applies to the graphical viewer, as far as I can tell.

Specified by:

setFocus in class AbstractPage

modelChanged

public void modelChanged(DESIViewModel old_model,
                         DESIViewModel new_model)

When the model changes, we need to keep a copy of the old model in case we decide to go back to it. I overrode this method:

Specified by:

modelChanged in class AbstractPage

Parameters:

new_model - DESIViewModel - The new model.

old_model - DESIViewModel - The old model.

AbstractPage.modelChanged(edu.usc.cse.desi.model.view.DESIViewModel, edu.usc.cse.desi.model.view.DESIViewModel)

undoButtonPressed

private void undoButtonPressed()

This method will be called when the Undo button is hit. It has a very simple function. If the member field myOldModel is not null, it will set it as the model.

runSamsAlgo

private void runSamsAlgo()

runAlgo

private void runAlgo(java.lang.String algo_name)

This method will run the algorithm whose name is passed in. This method is meant to be added to the selection listener on various algorithm buttons.

Parameters:

algo_name - String - The name of the algorithm that should be run.
