MergeNodes

public MergeNodes()

Method Details

getName

public String getName()

Description copied from interface: Algorithm

Returns the name (ID) of the 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.

getAcceleratorKeyStroke

public KeyStroke getAcceleratorKeyStroke()

Description copied from class: AbstractAlgorithm

Default: no accelerator for the menu item, created for this algorithm.

Specified by:

getAcceleratorKeyStroke in interface Algorithm

Overrides:

getAcceleratorKeyStroke in class AbstractAlgorithm

Returns:

NULL (default) if no accelerator should be assigned for this algorithm.

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

execute

public void execute()

Description copied from interface: Algorithm

Executes the whole algorithm.

Collection<Node> workNodes)

mergeNode

public static Node mergeNode(Graph graph,
Collection<Node> toBeMerged,
Vector2d center,
