Methods

allowNodeTurns

allowNodeTurns(args: { allow: boolean; nodeId: number }): void
Allow or disallow turns through the node.
Parameters
- args: { allow: boolean; nodeId: number }
  - allow: boolean
    If navigation through the node is allowed or not.
  - nodeId: number
    The id of the node.
Returns void
Throws
DataModelNotFoundError in case the node is not found in the WME data model

Throws
InvalidStateError if not allowed to edit node connections

getAll

getAll(): Node[]
Returns Node[]
an array of all the nodes in the WME data model

getById

getById(args: { nodeId: number }): null | Node
Parameters
- args: { nodeId: number }
  - nodeId: number
    An id of the node to find.
Returns null | Node
node with id, or null if not found in the WME data model

isVirtual

isVirtual(args: { nodeId: number }): boolean
Parameters
- args: { nodeId: number }
Returns boolean
boolean indicating whether the node is virtually connected to any segment.

Throws
DataModelNotFoundError If a node with the specified ID is not found in the data model.

moveNode

moveNode(args: { geometry: Point; id: number }): void
Moves a node to a new location on the map.

This method allows you to relocate an existing node to a different position. Note: Moving a node will affect all segments connected to that node, as the geometry of those segments will be modified to maintain the connection.
Parameters
- args: { geometry: Point; id: number }
  - geometry: Point
    The new geometry for the node to move.
  - id: number
    The id of the node to move.
Returns void
Throws
DataModelNotFoundError If a node with the specified ID is not found in the data model.

Throws
InvalidStateError If editing is not allowed or if the action to move the node fails.
