How to use the json-refs.getRefDetails function in json-refs

_.each(documentMetadata.original[modelDefsProp][modelId].allOf, function (schema, index) {
          var isInline = false;
          var parentPath;

          if (_.isUndefined(schema.$ref) || isRemotePtr(JsonRefs.getRefDetails(schema))) {
            isInline = true;
            parentPath = modelDefPath.concat(['allOf', index.toString()]);
          } else {
            parentPath = JsonRefs.pathFromPtr(schema.$ref);
          }

          // If the parent model does not exist, do not create its metadata
          if (!_.isUndefined(traverse(documentMetadata.resolved).get(parentPath))) {
            // Create metadata for parent
            getDefinitionMetadata(parentPath, isInline);

            modelMetadata.parents.push(JsonRefs.pathToPtr(parentPath));
          }
        });
