computePhases

public double[] computePhases(Iterator<Long> termIterator,
                              Map<Long,Integer> mapping,
                              Set<Long> interestingTerms)
                       throws Exception

Computes the phases for a set of terms

Parameters:

termIterator -

mapping - Internal mapping between a term id and a phase in the array, which is filled while processing the document if the term is interfering with another one

interestingTerms - Terms for which we have in interested in knowing the phase (null if all)

Returns:

An array of phases for which mapping provides the mapping

Throws:

Exception - if something goes wrong

processDocument

public void processDocument(Iterator<Long> termIterator,
                            Map<Cooccurrences.UnorderedPair,Cooccurrences.Statistics> statistics,
                            Set<Long> terms)

Process a document

Parameters:

termIterator - The iterator on terms

statistics - The statistics that we will collect

terms - The set of terms of the document

globalPairs - The set of pairs that have been detected at a global level

init

public void init(Mapping<String,Long> mappingAdaptator)
          throws IOException

Throws:

IOException

execute

public int execute()
            throws Throwable

Overrides:
