Class RN

All Implemented Interfaces:
AttributeChangeListener, Transformation, Manageable, PersistenceCapable, Shareable, UserFields, XObject, Map, Serializable

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.

    • preTransform

      public void preTransform(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
    • postTransform

      public void postTransform(Object object, boolean asNode, Matrix4d in, Matrix4d out, 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

    • 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
