### Node Graph
|
|
|
|
|
|
- Node graph can be used to create node diagrams, node have inputs and outputs sockets that can be connected using node connectors.
|
|
|
-- Data flows between the nodes, each node class has to implement how its data is processed using the `getValue()` method of its sockets.
|
|
|
+- Data flows between the nodes, each node class has to implement how its data is processed using the `getValue()` method of its sockets. This method is called across the nodes connected together to retrieve the result at any point.
|
|
|
+
|
|
|
+```javascript
|
|
|
+registerSockets()
|
|
|
+{
|
|
|
+ this.a = this.addInput("number", "a");
|
|
|
+ this.b = this.addInput("number", "b");
|
|
|
+
|
|
|
+ this.r = this.addOutput("number", "r");
|
|
|
+ this.r.getValue = () =>
|
|
|
+ {
|
|
|
+ // Add input A and input B
|
|
|
+ return this.a.getValue() + this.b.getValue();
|
|
|
+ };
|
|
|
+}
|
|
|
+```
|
|
|
+
|
|
|
- The node value propagates trough the node connections from outputs to inputs.
|
|
|
- Its possible to integrate user input elements using the DOM wrapper object.
