Class: NMEAPlus::Message::NMEA::NMEAMessage
- Defined in:
- lib/nmea_plus/message/nmea/base_nmea.rb
Overview
The base class for NMEA messages includes a few NMEA-specific parsing functions beyond the base NMEA class.

Class Method Summary collapse
-
._10_boolean(field) ⇒ bool
Convert a string true/false (encoded as 1=true, 0=false) to boolean.
-
._av_boolean(field) ⇒ bool
Convert a string true/false (encoded as A=true, V=false) to boolean.

Instance Attribute Details
#message_type ⇒ String
The generic type of the NMEA message. NMEA message types are 5 characters (or so): the first 2 are the talker ID, and the remaining characters are the generic message type.

Class Method Details
._10_boolean(field) ⇒ bool
Convert a string true/false (encoded as 1=true, 0=false) to boolean. This function is meant to be passed as a formatter to Base.field_reader.
