NgramMapAddingCallback

public NgramMapAddingCallback(NgramMap<V> map,
                              java.util.List<int[]> failures)

Method Detail

call

public void call(int[] ngram,
                 int startPos,
                 int endPos,
                 V v,
                 java.lang.String words)

Description copied from interface: LmReaderCallback

Called for each n-gram

Specified by:

call in interface LmReaderCallback<V>

Parameters:

ngram - The integer representation of the words as given by the provided WordIndexer

v - The value of the n-gram

words - The string representation of the n-gram (space separated)

handleNgramOrderFinished

public void handleNgramOrderFinished(int order)

Description copied from interface: NgramOrderedLmReaderCallback

Called when all n-grams of a given order are finished

Specified by:

handleNgramOrderFinished in interface NgramOrderedLmReaderCallback<V>

cleanup

public void cleanup()

Description copied from interface: LmReaderCallback

Called once all reading is done.

Specified by:

cleanup in interface LmReaderCallback<V>

initWithLengths

public void initWithLengths(java.util.List<java.lang.Long> numNGrams)

Description copied from interface: ArpaLmReaderCallback

Called initially with a list of how many n-grams will appear for each order.

Specified by:

initWithLengths in interface ArpaLmReaderCallback<V>

Parameters:

numNGrams - maps n-gram orders to number of n-grams (i.e. numNGrams.get(0) is the number of unigrams)

getFailures

public java.util.List<int[]> getFailures()

handleNgramOrderStarted

public void handleNgramOrderStarted(int order)

Description copied from interface: NgramOrderedLmReaderCallback

Called when n-grams of a given order are started

Specified by:

handleNgramOrderStarted in interface NgramOrderedLmReaderCallback<V>
