public class RN
extends Tropism
implements AttributeChangeListener

An RN(x,s) node represents a rotation which implements a positional tropism towards the location of node x. The Tropism.strength of the tropism is given by s.
This class declares the predicate RN.Pattern to allow one to write RN(x,s) in a pattern of an XL query.

Method Detail

attributeChanged

public void attributeChanged(AttributeChangeEvent event)
Specified by:
attributeChanged in interface AttributeChangeListener

getNTypeImpl

protected Node.NType getNTypeImpl()
Description copied from class: Node
This method returns the Node.NType which describes the managed fields of the class of this node. This method has to be implemented in every concrete subclass.

Overrides:
getNTypeImpl in class Node
Returns:
type describing the managed fields of the class of this node

newInstance

protected Node newInstance()
Description copied from class: Node
This method returns a new instance of the class of this node. This method has to be implemented in every concrete subclass.

Overrides:
newInstance in class Node
Returns:
new instance of class of this node

postTransform

public void postTransform(java.lang.Object object,
                          boolean asNode,
                          Matrix4d in,

                          Matrix4d pre,
                          GraphState gs)
Description copied from interface: Transformation
Implements the change from object's transformation in to the object's post-transformation out.

Specified by:
postTransform in interface Transformation
Parameters:
object - the object for which the transformation is computed
asNode - is object a node or an edge?
in - the transformation of the object
out - the post-tranformation of the object to be computed
pre - the post-transformation of the object's parent
gs - the graph state in which the computation has to be done

preTransform

public void preTransform(java.lang.Object object,
                         boolean asNode,
                         Matrix4d in,
                         Matrix4d out,
                         GraphState gs)
Description copied from interface: Transformation
Implements the change from the parent's post-transformation in to the object's transformation out.

Specified by:
preTransform in interface Transformation
Parameters:
object - the object for which the transformation is computed
asNode - is object a node or an edge?
in - the post-transformation of the object's parent
out - the tranformation of the object to be computed
gs - the graph state in which the computation has to be done
