Optional allowWhether or not to allow edges from this vertex back to itself. Defaults to true.
This flag will not prevent an edge from a port back to the node/group to
which it belongs - for that, see allowVertexLoopback.
Optional allowWhether or not to allow edges from a port back to the vertex it belongs to. Defaults to true.
Optional anchorSpec for anchors connected to this port
Optional anchorOffset, in pixels, to apply to the position in the x axis after the anchorX value has been
used to compute its default position.
Optional anchorOffset, in pixels, to apply to the position in the y axis after the anchorY value has been
used to compute its default position.
Optional anchorThe orientation in the x axis for connections attached to an anchor created for this port.
Optional anchorThe orientation in the y axis for connections attached to an anchor created for this port.
Optional anchorOptional 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 the Toolkit will use its own computed value. Note that the return value from this method is ArrayAnchorSpec,
meaning an array in the format [ x, y, orientationX, orientationY, offsetX, offsetY ]. Note also that offsetX and offsetY are optional,
and will be defaulted to 0.
Optional anchorOptional array of anchor positions to use.
Optional anchorXThe x location of any anchors created for this port. Allows you to specify where, in proportional values, the anchor should be located in the x axis. For a full discussion of how to use this (and the other anchor properties in this interface), see the documentation for anchors.
Optional anchorYThe y location of any anchors created for this port. Allows you to specify where, in proportional values, the anchor should be located in the y axis.
Optional edgeType of edges generated by this port.
Optional endpointIf isEndpoint is set to true, you can provide a spec for the endpoint with this parameter.
Optional eventsOptional map of event bindings.
Optional hoverIf isEndpoint is set to true, you can provide a spec for the endpoint's hover paint style with this parameter.
Optional isIf true, the port is rendered as an endpoint. By default this is false (meaning the port is represented by some DOM element that you have rendered).
Optional isWhether or not the port can act as a source for dragged connections. Defaults to false.
Optional isWhether or not the port can act as a target for dragged connections. Defaults to false.
Optional maxMaximum number of connections this vertex supports. Default is 1. A value of -1 means no limit.
Optional mergeWhen 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'.
Optional paintIf isEndpoint is set to true, you can provide a spec for the endpoint's paint style with this parameter.
Optional parametersA map of parameters that the template engine will merge with the backing data when rendering the vertex.
Optional parentOptional 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.
Optional templateTemplate to use for a vertex of this type. This is only for 'vanilla' Toolkit: if you are using an integration such as React/Angular/Vue/Svelte, you
will not need to provide this. If you provide this and also templateId, this will take precedence.
Optional templateID of the template to use for a vertex of this type. This is only for 'vanilla' Toolkit: if you are using an integration such as React/Angular/Vue, you
will not need to provide this. This parameter is distinct from template in that when you provide templateId you are expecting the Toolkit to resolve
the template for you, either from a templates block in a render call, or by looking for a script element in the DOM with the appropriate ID. If you
provide this and also template, template will take precedence.
Optional uniqueNormally, each time a new connection is established a port on which isEndpoint is set to true, a new
endpoint is created for that connection. Setting this flag will cause the Toolkit to only ever create a
single endpoint for the port, to which all connections should be attached. Note that you may wish to
consider the maxConnections parameter if you use this, as by default the endpoint will be created with
a limit of 1 connection.
