The ReferenceResolver can be used to resolve unresolved references, i.e. instances of class UnresolvedReference
There are two ways how this can be used:
1. the identifiers and associated model elements are added upfront using +add_identifier+ 2. register an :identifier_resolver with the constructor, which will be invoked for every unresolved identifier
Create a reference resolver, options:
:identifier_resolver: a proc which is called with an identifier and which should return the associated element in case the identifier is not uniq, the proc may return multiple values default: lookup element in internal map
Tries to resolve the given unresolved_refs. If resolution is successful, the proxy object will be removed, otherwise there will be an error description in the problems array. In case the resolved target element‘s type is not valid for the given feature, the target_type_error flag will be set on the unresolved reference. Returns an array of the references which are still unresolved. Options:
:problems an array to which problems will be appended :on_resolve a proc which will be called for every sucessful resolution, receives the unresolved reference as well as to new target element :use_target_type use the expected target type to narrow the set of possible targets (i.e. ignore targets with wrong type) :failed_resolutions a Hash which will receive an entry for each failed resolution for which at least one target element was found (wrong target type, or target not unique). hash key is the uref, hash value is the target element or the Array of target elements
