Class VisualNode

  +--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:

2.20 - May 7, 2002

Method Summary

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).
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).

Method Detail

getPosition

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 called GetNodeVisPosition_bn.

See Also:

setPosition		Sets it
Node.visual		Gets a VisualNode to work with

setPosition

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 called SetNodeVisPosition_bn.

See Also:

getPosition		Retrieves coordinates
Node.visual		Gets a VisualNode to work with

Example:

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