Accessors

graph

get graph(): undefined | Graph
The graph instance the node is placed in. undefined if the node hasn't been placed in a graph yet.

Returns undefined | Graph
Inherited from Node.graph
- Defined in core/src/node.ts:74

title

get title(): string
Customizable display name of the node.

Returns string
Inherited from Node.title

set title(v: string): void
Parameters
- v: string
Returns void
Inherited from Node.title
- Defined in core/src/node.ts:82

Methods

`Protected`addInput

addInput(key: string, input: NodeInterface): boolean
Add an input interface to the node
Parameters
- key: string
  Key of the input

`Protected`addOutput

addOutput(key: string, output: NodeInterface): boolean
Add an output interface to the node
Parameters
- key: string
  Key of the output
- output: NodeInterface
  The output instance
Returns boolean
True when the output was added, otherwise false (prevented by an event handler)
Inherited from Node.addOutput
- Defined in core/src/node.ts:105

onDestroy

onDestroy(): void
Override this method to perform cleanup when the node is deleted

Returns void
Inherited from Node.onDestroy
- Defined in core/src/node.ts:176
