export declare abstract class BaseNode<T, Config> implements Node<T, Config> Implements: Node<T, Config>
| Constructor | Modifiers | Description |
|---|---|---|
| (constructor)(inputs, outputs) | Creates a new instance of the BaseNode |
| Property | Modifiers | Type | Description |
|---|---|---|---|

| _outputs | protected |
SocketName[] | |
| bindings | readonly |
NodeBinding<T>[] | |
| bindings$ | readonly |
Observable<NodeBinding<T>[]> | |
| config | Maybe<Config> | ||
| config$ | readonly |
Observable<Maybe<Config>> | |
| emit | protected |
(value: Maybe<T>, socketName?: SocketName) => void | Emits a new value into the named output socket |
| emitError | protected |
(error: unknown, socketName?: SocketName) => void | Emits a downstream error |
| id | NodeId | ||
| inputs | SocketName[] | ||
| isBindingRequired |
|
boolean | If 'isBindingRequired' is true (the default), then config-changes will not drive recomputes if no input bindings are present. |

| recalculate | protected |
(cause: string) => void | Calculate the value of this processing node. This may be invoked even if this processing node is not fully configured. recalculate() should account for this |
