com.storedobject.chart.GraphData.XYNode

All Implemented Interfaces:

ComponentPart, ComponentProperty

Enclosing class:

GraphData<N extends GraphData.Node>

public static class GraphData.XYNode
extends GraphData.Node

A concrete implementation of the GraphData.Node class representing a node in a 2D space. This class extends the base functionality of GraphData.Node to include x and y coordinates for spatial positioning and provides methods to manipulate and retrieve these coordinates.

Constructor Details

XYNode

public XYNode(String name)

Constructs an XYNode with the specified name. The node is initialized with null as its category.

Parameters:

name - the name of the node

XYNode

public XYNode(String name,
 GraphData.Category category)

Constructs an XYNode with the specified name and category. The x and y coordinates of the node are initialized to 0.

Parameters:

name - The name of the node.

category - The category of the node. It can be null.

XYNode

public XYNode(String name,
 double x,
 double y)

Creates an XYNode instance with the specified name, x and y coordinates.

Parameters:

name - The name of the node.

x - The x-coordinate of the node.

y - The y-coordinate of the node.

XYNode

public XYNode(String name,
 double x,
 double y,
 GraphData.Category category)

Constructs an instance of XYNode with the given name, x and y coordinates, and an optional category.

Parameters:

name - The name of the node.

x - The x-coordinate of the node's position in 2D space.

y - The y-coordinate of the node's position in 2D space.

category - The category associated with this node. Can be null if no category is specified.

Method Details

getX

public double getX()

Retrieves the x-coordinate of this node.

Returns:

The x-coordinate as a double value.

x

public GraphData.Node x(double x)

The current instance of the node with the updated x-coordinate.

setX

public void setX(double x)

Sets the x-coordinate for the node.

Parameters:

x - The x-coordinate to set.

getY

public double getY()

Retrieves the Y-coordinate value of this node.

Returns:

the Y-coordinate as a double.

y

public GraphData.Node y(double y)

Sets the y-coordinate value for the node and returns the node instance.

Parameters:

y - The y-coordinate value to set.

Returns:

The updated instance of the node with the new y-coordinate value.

setY

public void setY(double y)

Sets the y-coordinate value.

Parameters:

y - The y-coordinate to set.
