Overview

A connector drawn on a diagram between two DiagramElements. References the underlying Relationship (by id) and the source and target DiagramElements (by id). Carries ordered waypoints for routing plus the EA EDGE codes (1=top, 2=right, 3=bottom, 4=left, 5..8=diagonal variants) which tell the renderer where to anchor the line on each end.

IMPLICIT_TYPES =

EA encodes package nesting and other implicit relationships as connector rows in t_diagramlinks. These are typically not rendered as paths in the SVG output — the containment is implied by visual position. However, when a connector has the tree style attribute (e.g. "V" for vertical tree routing), EA renders it as a real visible connector with a "+" marker at the contained end.

Instance Method Details

#renderable? ⇒ Boolean

True when this connector should appear in SVG output. False when hidden via the Hidden flag. Implicit-type connectors (e.g. Nesting) are filtered out UNLESS they carry a tree style attribute marking them as visible (basic.qea's "Package Contents" diagram has visible nesting; simple.qea's "Package Contents" diagram has invisible implicit nesting).

Returns:

  • (Boolean)
