#initialize(processor_name, result_name, converted_type = nil, converted_bit_size = nil) ⇒ ProcessorConversion

Returns a new instance of ProcessorConversion.

Parameters:

  • processor_name (String) —

    The name of the associated processor

  • result_name (String) —

    The name of the associated result in the processor

  • converted_type (String or nil) (defaults to: nil) —

    The datatype of the result of the processor

  • converted_bit_size (Integer or nil) (defaults to: nil) —

    The bit size of the result of the processor

#call(value, packet, buffer) ⇒ Varies

Returns The result of the associated processor.

Parameters:

  • value (Object) —

    The value to convert

  • packet (Packet) —

    The packet which contains the value. This can be useful to reach into the packet and use other values in the conversion.

  • buffer (String) —

    The packet buffer

Returns:

  • (Varies) —

    The result of the associated processor

  packet.processors[@processor_name].results[@result_name] || 0 # Never return nil
end

#to_config(read_or_write) ⇒ String

Returns Config fragment for this conversion.

Parameters:

  • read_or_write (String) —

    Either 'READ' or 'WRITE'

Returns:

  • (String) —

    Config fragment for this conversion
