Member Function Documentation

DBManager * QryBasedSampler::getDBManager (    )

Get a reference to the database manager.

int QryBasedSampler::getDocsPerQuery (    )

Get the number of documents per query used.

FreqCounter * QryBasedSampler::getFreqCounter (    )

Get a reference to the frequency counter.

int QryBasedSampler::getNumDocs (    )

Get the number of unique documents to retrieve.

int QryBasedSampler::getNumQueries (    )

Get the number of queries to run.

int QryBasedSampler::getNumWords (    )

Get the number of unique words to retrieve.

char * QryBasedSampler::getOutputPrefix (    )

Get the output prefix.

int QryBasedSampler::getTermMode (    )

Get the termination mode.

bool QryBasedSampler::probe (  char *    initQuery )

Probe the database, using initQuery as the initial query.

void QryBasedSampler::setDBManager (  DBManager *    database )

Set the dstabase manager.

void QryBasedSampler::setDocsPerQuery (  int    n )

Set the number of documents per query to use.

void QryBasedSampler::setFreqCounter (  FreqCounter *    counter )

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

void QryBasedSampler::setNumDocs (  int    n )

Set the number of unique documents to retrieve.

void QryBasedSampler::setNumQueries (  int    n )

Set the number of queries to run.

void QryBasedSampler::setNumWords (  int    n )

Set the number of unique words to retrieve.

void QryBasedSampler::setOutputPrefix (  char *    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 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
