VertexMapping

Base mapping for nodes, groups and ports.

Name	Type	Description
allowLoopback?	boolean	Whether or not to allow edges from this vertex back to itself. Defaults to false.
allowVertexLoopback?	boolean	Whether or not to allow edges from a port back to the vertex it belongs to. Defaults to true.
anchorPositionFinder?	AnchorPositionFinder<any>	Optional function to call on connection drop, to determine the location for the target anchor for the new connection. Returning null from this indicates no preference, and VisuallyJs will use its own computed value.
anchorPositions?	Array<ObjectAnchorSpec>	Optional array of anchor positions to use.
edgeType?	string	Type to assign to edges connected to this vertex as a source.
events?	EVT	Optional map of event bindings.
maxConnections?	number	Maximum number of connections this vertex supports. Default is 1. A value of -1 means no limit.
mergeStrategy?	string	When merging a type description into its parent(s), values in the child for connector, anchor and anchors will always overwrite any such values in the parent. But other values, such as overlays, will be merged with their parent's entry for that key. You can force a child's type to override every corresponding value in its parent by setting mergeStrategy:'override'.
parent?	string | Array<string>	Optional ID of one or more edge definitions to include in this definition. The child definition is merged on top of the parent definition(s). Circular references are not allowed and will throw an error.
