## Detailed Description

Dummy Encoding class.

A dummy encoder class that simply passes the input to the output. It is meant to allow us to easily use the FEC API encoder and decoder blocks in an application with no coding.

## Member Function Documentation

## make()

generic_encoder::sptr gr::fec::code::dummy_encoder::make | ( | int | frame_size,
|  | bool | pack = false,
|  | bool | packed_bits = false )

static

Build a dummy encoding FEC API object.

Parameters

  frame_size | Number of bits per frame. If using in the tagged stream style, this is the maximum allowable number of bits per frame.
  pack | Determines how to handle the input data stream as packed or unpacked bits. If set to True, the encoder's get_input_conversion will be set to 'pack', meaning that the data must be packed before being sent to this encoder. Generally handled through an extended encoder interface.
  packed_bits | Determines how the output data stream is handled. If set to True, the encoder's get_output_conversion returns 'packed_bits', meaning that the output data of the encoder is packed and should be unpacked. Generally handled through an extended encoder interface.

## rate()

double gr::fec::code::dummy_encoder::rate | ( |  | ) |

override pure virtual

Returns the coding rate of this encoder (it will always be 1).

Implements gr::fec::generic_encoder.

## set_frame_size()

bool gr::fec::code::dummy_encoder::set_frame_size | ( | unsigned int | frame_size | ) |

override pure virtual

Sets the uncoded frame size to `frame_size`. If `frame_size` is greater than the value given to the constructor, the frame size will be capped by that initial value and this function will return false. Otherwise, it returns true.

Implements gr::fec::generic_encoder.
