onClone

• onClone(): void
• Virtual

  Invoked when the node was cloned, invoked after invoking GraphPin.onClone.

  Returns void

onCreate

• onCreate(): void

• Called when the node has been instanced and is about to be added to a graph. This is a good place to initialize the default values for the node pins as it will then not be done during deserialization, which might otherwise discard newly instances values immediately.

  Returns void

  Parameters

  • data: ControlFlowData

  Returns GraphConnection

  Note

  Override this method with your node's control-flow execution logic. Implementing classes must call super. Data that is calculated as part of the execution must be stored in the GraphExecutionState that is available through the ControlFlowData. Stored data must be returned for the corresponding input pin in onRequestValue.

onFieldValueChanged

• Virtual

  Invoked when an inspectable field data was changed through the UI.

  Parameters

onPinDisconnected

• onPinDisconnected(pin, connection): void
• Virtual

  Invoked when a GraphPin was disconnected.

  Parameters

  Returns void

onPinValueChanged

• onPinValueChanged(pin, nodeReflectionData, pinReflectionPin): void
• Virtual

  Invoked when the pin field data was changed through the UI.

  Parameters

  • pin: GraphPin
  • nodeReflectionData: GraphNodeReflectionData
  • pinReflectionPin: GraphPinReflectionData

  Returns void

  Returns void

onRequestValue

• onRequestValue(pin, executionState): any

• Returns the value for the specified GraphPin.

  Parameters

  • pin: GraphPin
  • executionState: GraphExecutionState

  Returns any

  Note

  Data from previous executions should be retrieved through the GraphExecutionState.

onSerialize

• onSerialize(): void

• Invoked when serialization begins by the owning Graph.

  Returns void

registerOutdatedConnection

• registerOutdatedConnection(pin, connection): void

• Registers an outdated GraphConnection if it wasn't enabled during initialization. Outdated connections are attempted to be re-enabled during the call to enable

  Parameters

  • pin: GraphPin
  • connection: GraphConnection

  Returns void

removePin

• removePin(pin): void

• Removes a GraphPin.

  Parameters

  • pin: GraphPin

  • key: string

  Returns void

setUserData

• setUserData<T>(key, value): void

• Sets the user data key to the specified value.

  Type Parameters

  • T

  Parameters

  • key: string

    A key that uniquely identifies the property to be defined.
  • value: T

    The value to set the property to. The value type must support serialization.

  Returns void

synchronizePinsWithReflectionData

• synchronizePinsWithReflectionData(): void

• Synchronizes the node pins with the reflection data by adding missing pins and removing superfluous pins on the node.

toString

• toString(): string

• Returns a string representation of an object.

  Returns string

validate

• validate(validationStatus): GraphValidationStatus
• Virtual

  Ensures that the state of the node is valid.

  Parameters

  • validationStatus: Map<GraphObject, string>

  Returns GraphValidationStatus

  Note

  Implementing classes must call super. The method is typically called after deserialization or major edits to the graph. If validation fails, error information must be added to the validationStatus map.

• withBlockedEvents(callback): void

• Invokes the callback while prevent events to be dispatched.
