    return self
  end
  raise ArgumentError, "Invalid arguments when calling batch(#{argsList})"

- (void) close { ... }

This method returns an undefined value.

Like #close but notifies the completionHandler when it's closed.

Yields:

  • (ArgumentError)

  end
  raise ArgumentError, "Invalid arguments when calling close()"
end

- (::ReactivePgClient::PgStream) create_stream(fetch = nil, args = nil)

Execute the prepared query with a cursor and createStream the result. The createStream opens a cursor with a fetch size to fetch the results.

Note: this requires to be in a transaction, since cursors require it.

Parameters:

  • fetch (Fixnum) (defaults to: nil) —
    the cursor fetch size
  • args (::ReactivePgClient::Tuple) (defaults to: nil) —
    the prepared query arguments

Returns:

Raises:

  • (ArgumentError)
