Class CyGroupImpl

java.lang.Object
  cytoscape.groups.CyGroupImpl

All Implemented Interfaces:

CyGroup

public class CyGroupImpl
extends Object
implements CyGroup

The CyGroup class provides the implementation for a group model that maintains the list of nodes belonging to a group, the parent of a particular group, and the node that represents the group. Group information is stored in the CyGroup itself, as well as in special group attributes that are associated with the network, nodes, and edges involved. These attributes provide a natural mechanism for the saving and restoration of groups. There are also opaque flags

Method Detail

getGroupName

public String getGroupName()

Return the name of this group

Specified by:

getGroupName in interface CyGroup

setGroupName

public void setGroupName(String name)

Set the name of this group

getNodes

public List<CyNode> getNodes()

Get all of the nodes in this group

Specified by:

getNodes in interface CyGroup

Returns:

list of nodes in the group

getGroupNode

public CyNode getGroupNode()

Get the CyNode that represents this group

Specified by:

getGroupNode in interface CyGroup

Returns:

CyNode representing the group

getNodeIterator

public Iterator<CyNode> getNodeIterator()

Get an iterator over all of the nodes in this group

Specified by:

getNodeIterator in interface CyGroup

Returns:

node iterator

getInnerEdges

public List<CyEdge> getInnerEdges()

Get all of the edges completely contained within this group

Specified by:

getInnerEdges in interface CyGroup

Returns:

list of edges in the group

getOuterEdges

public List<CyEdge> getOuterEdges()

Get all of the edges partially contained within this group

Specified by:

getOuterEdges in interface CyGroup

Returns:

list of edges in the group

addOuterEdge

public void addOuterEdge(CyEdge edge)

Add an outer edge to the map. Some viewers may need to do this if they add and remove edges, for example.

Specified by:

addOuterEdge in interface CyGroup

Parameters:

edge - the CyEdge to add to the outer edge map

addInnerEdge

public void addInnerEdge(CyEdge edge)

Add an inner edge to the map. Some viewers may need to do this if they add and remove edges, for example.

Specified by:

addInnerEdge in interface CyGroup

Parameters:

edge - the CyEdge to add to the innter edge map

contains

public boolean contains(CyNode node)

Determine if a node is a member of this group

Specified by:

contains in interface CyGroup

Parameters:

node - the CyNode to test

Returns:

true if node is a member of the group

setState

public void setState(int state)

Set the state of the group. Setting the state of a group has two byproducts. First, the attribute "__groupState" is set to the state value to allow persistance across saves and restores. Second, if there is a viewer for this group, it is informed that the state has changed. This is used by the metaNode viewer, for example to provide programmatic control of whether the group is expanded or collapsed.

Specified by:

setState in interface CyGroup

Parameters:

state - the state to set

getState

public int getState()

Get the state of the group

Specified by:

getState in interface CyGroup

Returns:

group state

setViewValue

public void setViewValue(Object viewValue)

Set the viewValue for the group

Parameters:

viewValue - the view value to set

getViewValue

public Object getViewValue()

Get the viewValue for the group

Returns:

the view value

toString

public String toString()

Provide the default toString method

Specified by:

toString in interface CyGroup

Overrides:

toString in class Object

Returns:

group name

getViewer

public String getViewer()

Get the name of the viewer for this group

Specified by:

getViewer in interface CyGroup

Returns:

viewer for this group

addNode

public void addNode(CyNode node)

Add a new node to this group

Specified by:

addNode in interface CyGroup

Parameters:

node - the node to add

removeNode

public void removeNode(CyNode node)

Remove a node from a group

Specified by:

removeNode in interface CyGroup

Parameters:

node - the node to remove
