annotationVisible

source

Read only. The source element of the edge; i.e., the element at the tail-end of the edge.

target

Read only. The target element of the edge; i.e., the element at the head-end of the edge.

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 )
