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 prefix.docs 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
