Method Details

getLayout

CyLayoutAlgorithm getLayout(String name)

Returns a layout algorithm of the specified name and null if no algorithm exists with that name.

Parameters:

name - The name of the algorithm.

Returns:

a layout algorithm of the specified name and null if no algorithm exists with that name.

getAllLayouts

Collection<CyLayoutAlgorithm> getAllLayouts()

Returns a collection of all available layouts.

Returns:

a collection of all available layouts.

getDefaultLayout

CyLayoutAlgorithm getDefaultLayout()

Returns Cytoscape's default layout.

Returns:

the default layout.

setDefaultLayout

CyLayoutAlgorithm setDefaultLayout(CyLayoutAlgorithm layout)

Changes Cytoscape's default layout.

Parameters:

layout - The new default algorithm

getLayoutAttribute

String getLayoutAttribute(CyLayoutAlgorithm layout,
 CyNetworkView view)

Returns the attribute name that has been associated with the layout, or the empty string if there is no valid attribute associated to the layout for the given view. The attribute name may be a node or edge column name. Note, if an attribute was associated with the given layout using the setLayoutAttribute(CyLayoutAlgorithm, String) method, but the given CyNetworkView does not support that attribute, then the empty string will be returned instead.

Parameters:

view - If null returns the value set using setLayoutAttribute(CyLayoutAlgorithm, String). If view is not null then returns the attribute if it is valid for the given view. If the attribute is not valid for the given view then the empty string is returned.

Returns:

May return null if no attribute has been associated with the layout.

• CyLayoutAlgorithm.getSupportedNodeAttributeTypes()
• setLayoutAttribute(CyLayoutAlgorithm, String)

setLayoutAttribute

void setLayoutAttribute(CyLayoutAlgorithm layout,
 String layoutAttribute)

Associates an attribute name with the layout. This attribute may be passed as the layoutAttribute parameter to the CyLayoutAlgorithm.createTaskIterator(org.cytoscape.view.model.CyNetworkView, Object, java.util.Set, String) method when running the layout. The attribute name may be a node or edge column name.

Parameters:

layoutAttribute - May be null.
