    • setDelegate

      public static <T> T setDelegate(T potentialClosure, Object delegateWanted)
      Attempts to set delegate of object which might be a Closure.

      This usually happens when the object is functional interface or single abstract method class. Only the first use case is supported at the moment.

      The possibility of delegate being set should be documented with @DelegatesTo annotation (use provided scope to groovy dependency to retain the annotation to Groovy enabled projects).

      Type Parameters:
      T - the type of the object which might be backed by Groovy closure
      Parameters:
      potentialClosure - object which might be backed by Groovy closure
      delegateWanted - delegate to be set if the object is backed by Groovy closure
      Returns:
      always the original potentialClosure parameter which might have the delegate set if possible
