A mapper to encode/decode weighted transducers. Encoding of an Fst is useful for performing classical determinization or minimization on a weighted transducer by treating it as an unweighted acceptor over encoded labels.
The Encode mapper stores the encoding in a local hash table (EncodeTable) This table is shared (and reference counted) between the encoder and decoder. A decoder has read only access to the EncodeTable.
The EncodeMapper allows on the fly encoding of the machine. As the EncodeTable is generated the same table may by used to decode the machine on the fly. For example in the following sequence of operations
Encode -> Determinize -> Decode
we will use the encoding table generated during the encode step in the decode, even though the encoding is not complete.
