.handles?(_effective_type) ⇒ Boolean

Returns true if this kind handles the given effective connector type (e.g. "Aggregation", "Generalization").

.specs_for(_connector, _source, _target, _before_target, _after_source, relationship: nil) ⇒ Object

Returns an Array of Spec instances describing the markers to emit. Each Spec has :shape, :anchor, :base. relationship is the resolved relationship model (e.g. Association) when available, nil otherwise.
