All Implemented Interfaces:

Task

public abstract class AbstractPartitionLayoutTask
extends AbstractLayoutTask

This is a more helpful implementation of a LayoutAlgorithm Task that extends AbstractBasicLayoutTask and does the work of partitioning the CyNetworkView so that partitions may be laid out individually. Extensions of this class are meant to implement the layoutPartition() method and operate on the LayoutParition object that is passed to that method as an argument.

Cytoscape Backwards Compatibility (Abstract Class): This class is abstract and meant to be extended by users. This means that we may add methods for minor version updates. Methods will only be removed for major version updates.

AbstractPartitionLayoutTask

public AbstractPartitionLayoutTask(String displayName,
                                   boolean singlePartition,
                                   CyNetworkView networkView,

                                   UndoSupport undo)

Creates a new AbstractPartitionLayoutTask object.

Parameters:

name - The name of the layout algorithm.

singlePartition - Whether this layout algorithm should execute on a single partition instead of multiple partitions.

networkView - the CyNetworkView being partitioned.

nodesToLayOut - the set of nodes to layout.

layoutAttribute - the name of the attribute to use for this layout. Allowed to be empty or null.

Method Detail

layoutPartition

public abstract void layoutPartition(LayoutPartition partition)

Override this method and layout the LayoutPartion just like you would a NetworkView.

Parameters:

partition - The LayoutPartition to be laid out.

setTaskStatus

protected void setTaskStatus(int percent)

Used for

Parameters:

percent - The percentage of completion for this partition. Value must be between 0 and 100.

doLayout

public void doLayout(TaskMonitor taskMonitor)

AbstractGraphPartitionLayout implements the doLayout method of AbstractBasicLayout in which it calls the layoutParition method on each LayoutPartition object created for the network.

Specified by:

doLayout in class AbstractLayoutTask

Parameters:

taskMonitor - the TaskMonitor provided by the run() method of the Task.
