## norsys.netica
Class VisualNode

    java.lang.Object
      |
      +--norsys.netica.VisualNode

public class VisualNode
extends java.lang.Object

An object representing the visual aspects of a Netica Node as it would be displayed in the Netica Application.

This class does not have a public constructor; use `Node.visual` to retrieve an instance for a node.

Since:
  2.12
Version:
  3.25 - June 15, 2007

Method Summary
`Node` | `getNode()` Returns the Node that this VisualNode represents.
`double[]` | `getPosition()` Retrieves as elements 0 and 1 respectively, the x,y coordinates of the center of this node, as it would appear in a visual display (e.g., in Netica Application).
`java.lang.String` | `getStyle()` Returns the current "style descriptor" of this node for any visual display (e.g., in Netica Application, or within a NetPanel).
`void` | `setPosition(double x, double y)` Moves this node so that its center is at coordinates (x, y), for any visual display (e.g., in Netica Application).
`void` | `setStyle(java.lang.String style)` Sets the style of this node for any visual display (e.g., in Netica Application, or within a NetPanel).

Method Detail

public Node getNode ( )

  Returns the Node that this VisualNode represents.
  Version:
  Versions 3.0 and later have this method.

public double[] getPosition ( ) throws NeticaException

  Retrieves as elements 0 and 1 respectively, the x,y coordinates of the center of this node, as it would appear in a visual display (e.g., in Netica Application).
  Version:
  Versions 2.07 and later have this method.
  In the C Version of the API, this function is named GetNodeVisPosition_bn.
  See Also:

  setPosition |  | Sets it
  `Node.getNodesetColor` |  | Gets color
  `Node.visual` |  | Gets a VisualNode to work with

public String getStyle ( ) throws NeticaException

  Returns the current "style descriptor" of this node for any visual display (e.g., in Netica Application, or within a NetPanel).

  The returned string may be used as a parameter to setStyle.
  Version:

  Versions 3.05 and later have this method.
  In the C Version of the API, this function is named GetNodeVisStyle_bn.
  See Also:

  setStyle |  | Sets the style
  getPosition |  | Retrieves display coordinates
  `Node.visual` |  | Gets a VisualNode to work with

  Example:

       // if style of node is labelled_box, make it belief_bars, for display in Netica Application.
       String style= node.visual().getStyle();
       if ( style.startsWith( "labelled_box" ) ) {
         node.visual().setStyle ( "belief_bars" );
       }

       // copy style of node1 to node2, for display in Netica Application.
       node2.visual().setStyle ( node1.visual().getStyle() );

public void setPosition ( |
double | x,
double | y
| ) throws NeticaException

  Moves this node so that its center is at coordinates (x, y), for any visual display (e.g., in Netica Application).

  This is useful when directly programming Netica Application, or before writing a net to a file that will later be read by Netica Application.
  Parameters:

  double |  | x |  | desired horizontal pixel value
  double |  | y |  | desired vertical pixel value

  Version:
  Versions 2.07 and later have this method.
  In the C Version of the API, this function is named SetNodeVisPosition_bn.
  See Also:

  getPosition |  | Retrieves coordinates
  `Node.setNodesetColor` |  | Sets color
  `Node.visual` |  | Gets a VisualNode to work with

  Example:

        // lower node by 20 pixels for display in Netica Application.
        double[] pos = node.visual().getPosition();
        node.visual().setPosition (pos[0], pos[1]+20);

public void setStyle ( |
String | style
| ) throws NeticaException

  Sets the style of this node for any visual display (e.g., in Netica Application, or within a NetPanel).

  This is useful when directly programming Netica Application, or before writing a net to a file that will later be read by Netica Application.

  style must be one of: "Default", "Absent", "Shape", "LabeledBox", "BeliefBars", "BeliefLine", or "Meter". In future, other qualifiers may be added to this style parameter (e.g., "LabeledBox,CornerRoundingRadius=3,LineThickness=2").

  Note that setting the style does not guarantee that a particular display application will be able to display the node in that style. Some applications may be limited in their ability and may interpret a particular display style differently or even ignore it.
  Parameters:

  String |  | style |  | a style descriptor for the desired style

  Version:
  Versions 3.05 and later have this method.
  In the C Version of the API, this function is named SetNodeVisStyle_bn.
  See Also:

  getStyle |  | Gets style
  setPosition |  | Sets coordinates
  `Node.visual` |  | Gets a VisualNode to work with

  Example:

       // if style of node is labelled_box, make it belief_bars, for display in Netica Application.
       String style= node.visual().getStyle();
       if ( style.startsWith( "labelled_box" ) ) {
         node.visual().setStyle ( "belief_bars" );
       }

       // copy style of node1 to node2, for display in Netica Application.
       node2.visual().setStyle ( node1.visual().getStyle() );
