Constructor & Destructor Documentation

ace::NGramsProcessor::NGramsProcessor

(

NGramStore &

ngrams

)

[inline]

Pass n-gram store to n-grams processor to retrieve all *-frequencies.

Parameters:

ngrams

N-gram store.

Member Function Documentation

bool ace::NGramsProcessor::next

(

void

)

Counts values of frequency table for next N-gram.

Returns:

True, if there has been N-gram to process, otherwise return false.

const NGramFrequencies& ace::NGramsProcessor::ngram_frequencies

(

void

)

const [inline]

Frequencies object is returned by reference, so it stays valid till the following next() call.

Returns:

Last processed N-gram frequencies.
