#attributes ⇒ Hash

Returns Access the token details Hash object ruby’fied to use symbolized keys.

Returns:

  • (Hash) —

    Access the token details Hash object ruby’fied to use symbolized keys

  @hash_object
end

#capability ⇒ Hash

The capabilities associated with this Ably Token. The capabilities value is a JSON-encoded representation of the resource paths and associated operations. Read more about capabilities in the capabilities docs.

Returns:

  • (Hash) —

    Capabilities assigned to this token

    else
      JSON.parse(attributes.fetch(:capability))
    end
  end
end

#client_id ⇒ String

The client ID, if any, bound to this Ably Token. If a client ID is included, then the Ably Token authenticates its bearer as that client ID, and the Ably Token may only be used to perform operations on behalf of that client ID. The client is then considered to be an identified client.

Returns:

  • (String) —

    Optional client ID assigned to this token

end

#expired?(attributes = {}) ⇒ Boolean

Returns true if token is expired or about to expire For tokens that have not got an explicit expires attribute expired? will always return true

Parameters:

  • attributes (Hash) (defaults to: {})

Options Hash (attributes):

  • :from (Time) —

    Sets a current time from which token expires

Returns:

  • (Boolean)

  from = attributes[:from] || Time.now
  expires < from + TOKEN_EXPIRY_BUFFER
end

#expires ⇒ Time

The timestamp at which this token expires as milliseconds since the Unix epoch.

Returns:

  • (Time) —

    Time the token expires

end

#from_token_string? ⇒ Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

True if the TokenDetails was created from an opaque string i.e. no metadata exists for this token

Returns:

  • (Boolean)
