Detailed Description

template<class Holder>
class kaldi::RandomAccessTableReaderMapped< Holder >

This class is for when you are reading something in random access, but it may actually be stored per-speaker (or something similar) but the keys you're using are per utterance.

So you also provide an "rxfilename" for a file containing lines like utt1 spk1 utt2 spk1 utt3 spk1 and so on. Note: this is optional; if it is an empty string, we just won't do the mapping. Also, "table_rxfilename" may be the empty string (as for a regular table), in which case the table just won't be opened. We provide only the most frequently used of the functions of RandomAccessTableReader.
