#### Using `StreamingResponse` with file-like objects

If you have a file-like object (e.g. the object returned by `open()`), you can create a generator function to iterate over that file-like object.

That way, you don't have to read it all first in memory, and you can pass that generator function to the `StreamingResponse`, and return it.

          && getUpperBoundType().equals(r.getUpperBoundType())
          && Objects.equal(getLowerEndpoint(), r.getLowerEndpoint())
          && Objects.equal(getUpperEndpoint(), r.getUpperEndpoint());
    }
    return false;
  }

  @Override
  public int hashCode() {
    return Objects.hashCode(
        comparator,
        getLowerEndpoint(),
        getLowerBoundType(),

        return result;
      }
    }
    return 0;
  }

  @Override
  public boolean equals(@CheckForNull Object object) {
    if (object == this) {
      return true;
    }
    if (object instanceof CompoundOrdering) {
      CompoundOrdering<?> that = (CompoundOrdering<?>) object;
      return Arrays.equals(this.comparators, that.comparators);
    }
    return false;
