#include <ResultFile.hpp>

List of all members.

Public Methods

 ResultFile (bool TRECFormat=true)
 ~ResultFile ()
void openForRead (istream &is, Index &index)
 Open and associate an input stream for reading, e.g., with getResult function.

void load (istream &is, Index &index)
 Load all the results into an internal hash table, so as to allow random access to any of the results.

void getResult (char *expectedQID, IndexedRealVector &res)
 Read the results for a given query from the associated input stream into memory (stored in res), sequential reading, so appropriate order must be maintained and attempting to get the results for a query that has no results will fail.

bool findResult (char *queryID, IndexedRealVector *&res)
 Find the results for the given query id, the output variable res gets a pointer to the results, returns true iff found.

void openForWrite (ostream &os, Index &index)
 Associate an output stream for writing results.

void writeResults (char *queryID, IndexedRealVector *results, int maxCountOfResult)
 writing the results (stored in results) into the associated output stream, up to a maximum count.


Private Methods

bool readLine ()

Read the results for a given query from the associated input stream into memory (stored in res), sequential reading, so appropriate order must be maintained and attempting to get the results for a query that has no results will fail.

void ResultFile::load (  istream &    is,
Index &    index
) 
 

Load all the results into an internal hash table, so as to allow random access to any of the results.

void ResultFile::openForRead (  istream &    is,
Index &    index
) 
 

Open and associate an input stream for reading, e.g., with getResult function.

void ResultFile::openForWrite (  ostream &    os,
Index &    index
)  [inline]
 

Associate an output stream for writing results.
