code: public void loadGlue(Glue glue, Method method, Class<?> glueCodeClass) {
          this.glue = glue;
          methodScanner.scan(this, method, glueCodeClass);
      }
docs: Convenience method for frameworks that wish to load glue from methods explicitly (possibly
  found with a different mechanism than Cucumber's built-in classpath scanning).
  
  @param glue          where stepdefs and hooks will be added.
  @param method        a candidate method.
  @param glueCodeClass the class implementing the method. Must not be a subclass of the class implementing the method.
