  PathValue<X,S> findFirst()
  
  Description copied from interface: SearchStream

- findSingle
  
  PathValue<X,S> findSingle()
  
  Description copied from interface: SearchStream
  Find the only instance in the stream or null.
  Invoke this method only when you know that the result stream contains at most one value, e.g., when searching for an object by its value in a field with a unique constraint. If the stream actually contains multiple values, then invoking any of the "single value" SearchValue methods such as value() or toOptional() will generate a NonUniqueResultException.
  Using this method is preferable to using SearchStream.findFirst() or SearchStream.findAny() for the same purpose, because it not only actually verifies the uniqueness assumption, but it also makes that assumption clearer in the code.
  Example:
  final User user = qb.stream(User.class) .filter(u -> qb.equal(u.get(User_.username), username)) .findSingle() .orElseThrow(NoSuchUserException::new);
  Specified by:
  
  findSingle in interface ExprStream<X,S extends Path<X>>

  Returns:
  
  a single value, either the only instance in this stream or null if this stream is empty

  Bind an unbound reference to a new query root that will be added to the query.
  To select the new root in a SearchStream, use SearchStream.map(), providing a Function that returns ref.
  Note that this effectively creates an unconstrained (cross product) join with the new root. Typically there would be some additional restrictions imposed (e.g., via filter()) to relate the new root to the items in the stream.
  
  Specified by:
  
  addRoot in interface ExprStream<X,S extends Path<X>>
