Instance Method Details
#match?(value, depth: 0) ⇒ Boolean
For a node n and constraint value v, nodeSatisfies(n, v) if n matches some valueSetValue vsv in v. A term matches a valueSetValue if:
- vsv is a StemRange with stem st and exclusions excls and nodeIn(n, st) and there is no x in excls such that nodeIn(n, excl).
- vsv is a Wildcard with exclusions excls and there is no x in excls such that nodeIn(n, excl).
