Fields

Field	Type	Description
isEdge	boolean	Read only. Returns True.
weight	number	The edge weight, a float value normally between -1.0 and 1.0.
weightVisible	boolean	True if the edge weight is visible independently of the document’s edgeWeightsVisible setting.
annotationVisible	boolean	True if the edge annotation is visible independently of the document’s edgeAnnotationsVisible setting.
source	GraphElem	Read only. The source element of the edge; i.e., the element at the tail-end of the edge.
target	GraphElem	Read only. The target element of the edge; i.e., the element at the head-end of the edge.
isBackEdge	boolean	Read only. True if the edge is a back edge.
splines		Deprecated. Use splinesDictionary instead.
splinesDictionary	dictionary or None	Read only. The edge’s splines as a dictionary or None if the edge is hidden in a collapsed group. The keys are the The dictionary values are tuples of tuples of the spline control points.
arrowheadVertices	tuple or None	Read only. The edge’s arrowhead as a tuple of three tuples (x, y) or None if the edge is hidden in a collapsed group.
color	Color	The edge’s color in the canvas.
noteLines	list of LayoutLine	Read only. A list of LayoutLines providing position information for the annotation.

Methods

isWeightVisible()

True if the edge weight is visible either because weightVisible is True or the document’s edgeWeightsVisible setting is True, otherwise False.

isAnnotationVisible()

True if the edge annotation is visible either because annotationVisible is True or the document’s edgeAnnotationsVisible setting is True, otherwise False.

equals( object )

Returns True if object represents the same edge as self.
