# FLAC::Decoder::File Class Reference
[FLAC++/decoder.h: decoder classes]

`#include <decoder.h>`

Inheritance diagram for FLAC::Decoder::File:

List of all members.

## Detailed Description

This class wraps the FLAC__StreamDecoder. If you are not decoding from a file, you may need to use FLAC::Decoder::Stream.

The usage of this class is similar to FLAC__StreamDecoder, except instead of providing callbacks to FLAC__stream_decoder_init*_FILE() or FLAC__stream_decoder_init*_file(), you will inherit from this class and override the virtual callback functions with your own implementations, then call init() or init_off(). The rest of the calls work the same as in the C layer.

Only the write, and error callbacks from FLAC::Decoder::Stream are mandatory. The others are optional; this class provides full working implementations for all other callbacks and supports seeking.
