org.cytoscape.view.model

Interface View<S>

Type Parameters:

S - the base (model-level) object for which this is a View. For example, CyNode or CyEdge. In the future versions, Attributes can be this parameter.

All Superinterfaces:

CyIdentifiable

All Known Subinterfaces:

CyNetworkView, NullCyNetworkView

public interface View<S>
extends CyIdentifiable

The base interface that defines methods used to set visual properties for nodes, edges, and networks. Think of it as a row in the view-model table.

Cytoscape Backwards Compatibility (API Interface): We expect that this interface will be used but not implemented by developers using this interface. As such, we reserve the right to add methods to the interface as part of minor version upgrades. We will not remove methods for any changes other than major version upgrades.

Module: viewmodel-api

Method Detail

setVisualProperty

<T,V extends T> void setVisualProperty(VisualProperty<? extends T> vp,
                                       V value)

Assign a value to the given Visual Property of this view.

Type Parameters:

T - Data type of the visual property. This can be subclasses of type T.

V - Value of the visual property. This can be subclasses of T.

Parameters:

vp - the VisualProperty (Node Color, Edge Width, etc.)

value - actual value stored in this visual property.

getVisualProperty

<T> T getVisualProperty(VisualProperty<T> vp)

Get the actual value for the given visual property.

Type Parameters:

T - Object type of the Visual Property (Color, Double, ...)

Parameters:

vp - the VisualProperty.

Returns:

Value associated with this View and Visual Property pair.

isSet

boolean isSet(VisualProperty<?> vp)

Indicates whether or not the passed visual property is set with a non-null value.

Parameters:

vp - the VisualProperty.

Returns:

true if the view has a non-null value for the VisualProperty.

Parameters:

vp - the VisualProperty

Returns:

true if the given VisualProperty's value has been locked.

clearVisualProperties

void clearVisualProperties()
