public class SimpleNode extends Object implements INode
INode interface that can be used stand-alone.
Note that this class is not the one used as the default implementation of a DefaultGraph's INodes and
casting them to SimpleNode will fail.
Instances of this class can be used without an accompanying graph instance. All of the properties are mutable. An
example of a possible use case would be the rendering of a node into a graphics context: Simply create a
SimpleNode, associate a style with it and use the style's renderer instance to obtain a rendering for the
node.
| Constructor and Description |

The layout of a node is a rectangle in the world coordinate system that describes the bounding box of the representation
of a node. Since this method will yield a live view, it is up to the client to copy the values of the instance if a
snapshot of the state is needed. In order to modify the layout of a node, use the various methods
in IGraph.

This gives access to a read-only live view of the ports, i.e. the collection can change over time, as well as the ports contained in it. If a snapshot of the current state is needed, one needs to copy the collection.

INodeCanvasControl.
In order to set the style on an instance, use the IGraph.setStyle(INode, INodeStyle)
method. Note that the style instance associated with a node instance may be shared between multiple node instances and
that the modification of this style will result in a change of the appearance of all nodes that are associated with the
same style instance.
public final Object getTag()
ITagOwnerThe implementation itself does not normally depend on the tag associated with it. It serves as storage for the object only.

Typically, this method will be called in order to obtain a different view or
aspect of the current instance. This is quite similar to casting or using
a super type or interface of this instance, but is not limited to inheritance or
compile time constraints. An instance implementing this method is not
required to return non-null implementations for the types, nor does it
have to return the same instance any time. Also it depends on the
type and context whether the instance returned stays up to date or needs to
be reobtained for subsequent use.public final void setLabels(IListEnumerable<ILabel> value)
