def magnitude
  return nil unless sentiment?
  sentiment.magnitude
end

#offset ⇒ Integer Also known as: begin_offset

The beginning offset of the content in the original document. See TextSpan#offset.

The API calculates the beginning offset according to the client system's default encoding. In Ruby this defaults to UTF-8. To change the offset calculation you will need to change Ruby's default encoding. This is commonly done by setting Encoding.default_internal to Encoding::UTF_16 or Encoding::UTF_32. If the system is configured to use an encoding other than UTF-16 or UTF-32 the offset will be calculated using UTF-8.

Returns:

  • (Integer)
