Detailed Description

Class holds lemma and tag indices together.

It's quite likely that when processing large text corpora, the default schema (24 bits for lemma, 8 bits for tag) will require change - here's the only place that needs to be altered.


Constructor & Destructor Documentation

ace::TaggedLemma::TaggedLemma ( string_index_t  lemma,
tag_index_t  tag 
) [inline]

Parameters:

Lemma getter.

tag_index_t ace::TaggedLemma::tag ( void   )  const [inline]

Tag getter.


Member Data Documentation

union { ... } [private]

Lemma and tag are kept on the same address Lemma resides in 24 LSB bits.

Tag ressides in: 8 MSB bits.
