Class GraphData.ValueNode

java.lang.Object

com.storedobject.chart.GraphData.Node

com.storedobject.chart.GraphData.ValueNode

All Implemented Interfaces:

ComponentPart, ComponentProperty

Enclosing class:

GraphData<N extends GraphData.Node>

public static class GraphData.ValueNode
extends GraphData.Node

The ValueNode class represents a type of Node that holds a numerical value. It extends the base functionality of the Node class by adding a specific attribute to store and manage a numerical value. This value can be encoded into a JSON format when serializing the node. This class is useful for scenarios where nodes in a graph have associated numerical properties that need to be dynamically updated or serialized as part of its data.

Constructor Details

ValueNode

public ValueNode(Number value)

Constructs a ValueNode instance with the specified numerical value.

Parameters:

value - Numerical value to be associated with this node.

Method Details

getValue

public Number getValue()

Returns the numerical value held by this node.

Returns:

The numerical value as a Number.

setValue

public void setValue(Number value)

Sets the numerical value for this node.

Parameters:

value - The numeric value to set. It can be of any type that extends the Number class.

value
