Method Details

getCurrentNodeContextMenuItem

public JMenuItem[] getCurrentNodeContextMenuItem(Collection<Node> selectedNodes)

Description copied from interface: ProvidesNodeContextMenu

This method should be implemented, as that it returns the desired Context-MenuItem for the Plugin. It will be added on the fly to a newly created context menu, when the user right-clicks an EditorFrame. The plugin should implement the Interface SelectionListener if the menu item should be variable to the current selection. You could also return a MenuItem that contains a subMenu.

Specified by:

getCurrentNodeContextMenuItem in interface ProvidesNodeContextMenu

Returns:

MenuItem the menu item for the context menu

execute

public void execute()

Description copied from interface: Algorithm

Executes the whole algorithm.

Specified by:

execute in interface Algorithm

getName

public String getName()

Description copied from interface: Algorithm

Returns the name (ID) of the algorithm.

Specified by:

getName in interface Algorithm

Returns:

DOCUMENT ME!

getCategory

public String getCategory()

Description copied from interface: Algorithm

Returns the category an algorithm should assigned to. Return NULL if the algorithm should be sorted directly in the plugin menu.

Specified by:

getCategory in interface Algorithm

Overrides:

getCategory in class AbstractAlgorithm

Returns:

The category an algorithm should assigned to.

getSetCategory

public Set<Category> getSetCategory()

Description copied from interface: Algorithm

Returns a set of categories to classify this algorithm . e.g. return new HashSet(Arrays.asList( Category.GRAPH, Category.NODE )); is an algorithm, working on graphs and more specific on nodes

Specified by:

getSetCategory in interface Algorithm

Overrides:

getSetCategory in class AbstractAlgorithm

Returns:

Set of Category Enums that classify this algorithm.

getDescription

public String getDescription()

Description copied from class: AbstractAlgorithm

The algorithm description.

Specified by:

getDescription in interface Algorithm

Overrides:

getDescription in class AbstractAlgorithm

Returns:

String, could be HTML-styled.

check

public void check()
           throws PreconditionException

Description copied from interface: Algorithm

Checks whether all preconditions of the current graph are satisfied.

Specified by:

check in interface Algorithm

Overrides:

check in class AbstractAlgorithm

Throws:

PreconditionException - if the preconditions of the current graph are not satisfied.

getParameters

public Parameter[] getParameters()

Description copied from interface: Algorithm

Returns a list of Parameter that are set for this algorithm.

Specified by:

getParameters in interface Algorithm

Overrides:

getParameters in class AbstractAlgorithm

Returns:

a collection of Parameter that are needed by the Algorithm.

setParameters

public void setParameters(Parameter[] params)

Description copied from interface: Algorithm

Sets the parameters for this algorithm. Must have the same types and order as the array returned by getParameter.

Specified by:

setParameters in interface Algorithm

Overrides:

setParameters in class AbstractAlgorithm

Parameters:

params - Parameter array
