Member Function Documentation

const lemur::distrib::DBManager * lemur::distrib::QryBasedSampler::getDBManager  )  const

Get a reference to the database manager.

int lemur::distrib::QryBasedSampler::getDocsPerQuery  )  const

Get the number of documents per query used.

const lemur::distrib::FreqCounter * lemur::distrib::QryBasedSampler::getFreqCounter  )  const

Get a reference to the frequency counter.

int lemur::distrib::QryBasedSampler::getNumDocs  )  const

Get the number of unique documents to retrieve.

int lemur::distrib::QryBasedSampler::getNumQueries  )  const

Get the number of queries to run.

int lemur::distrib::QryBasedSampler::getNumWords  )  const

Get the number of unique words to retrieve.

const string & lemur::distrib::QryBasedSampler::getOutputPrefix  )  const

Get the output prefix.

int lemur::distrib::QryBasedSampler::getTermMode  )  const

Get the termination mode.

bool lemur::distrib::QryBasedSampler::probe const char *  initQuery  ) 

Probe the database, using initQuery as the initial query.

void lemur::distrib::QryBasedSampler::setDBManager const DBManager database  ) 

Set the dstabase manager.

void lemur::distrib::QryBasedSampler::setDocsPerQuery int  n  ) 

Set the number of documents per query to use.

void lemur::distrib::QryBasedSampler::setFreqCounter FreqCounter counter  ) 

Set the frequency counter - this handles building the database description from documents.

void lemur::distrib::QryBasedSampler::setNumDocs int  n  ) 

Set the number of unique documents to retrieve.

void lemur::distrib::QryBasedSampler::setNumQueries int  n  ) 

Set the number of queries to run.

void lemur::distrib::QryBasedSampler::setNumWords int  n  ) 

Set the number of unique words to retrieve.

void lemur::distrib::QryBasedSampler::setOutputPrefix const string &  prefix  ) 

Set the ouput prefix - this prepended to the file names for documents and models. Documents are stored in and the model for a db is stored in prefix.model.

void lemur::distrib::QryBasedSampler::setTermMode int  m  ) 

Set the termination mode. To specify a disjunction of conditions, OR the modes together.

T_NDOCS - terminate on number of unique docs retrieved T_NWORDS - terminate on number of unique words retrieved T_NQRYS = terminate on number of quries run
