Member Function Documentation

ActiveDB * LServer::active (   )  [virtual]

News retrieval function. Returns: Pointer to the active database. The database pointed to by the return vlue is maintained by the LServer class. Hence, it should not be modified by the user and must not be deleted! Implements NServer. Reimplemented in CServer. Definition at line 131 of file NServer.cc. { return _ActiveDB; }

Newsgroup * LServer::getgroup (  const char *  name  )  [virtual]

Return the newsgroup with name >name<. If the newsgroup does not exist, NULL will be returned. Parameters: name  Name of the newsgroup Returns: Pointer to a Newsgroup structure. Free it by calling the freegroup method. The newsgroup must be destructed by the same Server-instance it was constructed from. Exceptions: NoSuchGroupError  If the newsgroup does not exist Implements NServer. Reimplemented in CServer. Definition at line 154 of file NServer.cc. References _SpoolDirectory, ERROR_LOCATION, ActiveDB::hasgroup(), slog, and VERB. { VERB(slog. p(Logger::Debug) << "LServer::getgroup(" << name << ")\n"); if (!_ActiveDB->hasgroup(name)) throw NoSuchGroupError("no such group", ERROR_LOCATION); return new NVNewsgroup(_OverviewFormat, _SpoolDirectory, name); }

GroupInfo * LServer::groupinfo (  const char *  name  )  [virtual]

Parameters: name  Name of the newsgroup Returns: Returns informations of the newsgrup in statically allocated GroupInfo structure. Exceptions: NoSuchGroupError  If the group does not exist Implements NServer. Reimplemented in CServer. Definition at line 136 of file NServer.cc. References ASSERT, ERROR_LOCATION, ActiveDB::get(), slog, and VERB. Referenced by CServer::groupinfo(). { VERB(slog. p(Logger::Debug) << "LServer::groupinfo(" << name << ")\n"); static GroupInfo agroup; ASSERT(if (strlen(name) > 512) { throw AssertionError ("LServer::groupinfo: name of newsgroup too long\n", ERROR_LOCATION);} ); if (_ActiveDB->get(name, &agroup) < 0) throw NoSuchGroupError("no such group", ERROR_LOCATION); return &agroup; }

void LServer::init (  const char *  spooldir  )  [protected]

Definition at line 109 of file NServer.cc. References _SpoolDirectory, ASSERT, ERROR_LOCATION, MAXGROUPNAMELEN, pSpool, slog, and VERB. Referenced by CServer::CServer(), and LServer(). { VERB(slog. p(Logger::Debug) << "LServer::init(" << spooldir << ")\n"); ASSERT(if (strlen(spooldir) > sizeof(_SpoolDirectory) - MAXGROUPNAMELEN - 16) { throw AssertionError ("name of spooldirectory too long. longest groupname+spooldirlength does not fit into maxpathlen", ERROR_LOCATION);} ); strcpy(_SpoolDirectory, spooldir); pSpool = new ArtSpooler(spooldir); if (!_OverviewFormat) _OverviewFormat = new OverviewFmt(); if (!_ActiveDB) _ActiveDB = NULL; }

int LServer::post (  Article *  article  )  [virtual]

Post an article to the news server. Parameters: article  The article to be posted. Returns: 0 on success, otherwise <0 Bug: Not yet supported Todo: implement this method Implements NServer. Reimplemented in CServer. Definition at line 163 of file NServer.cc. { // TRACE(ctrace << "LServer::post(Article*)\n"); // char fn[1024]; // fstream fs; // int qnbr; // sprintf(fn,".outgoing/.qnbr"); // fs.open(fn,ios::in|ios::out); // fs >> qnbr; // if(!fs.good()) { // qnbr=0; // fs.clear(); // } // fs.seekp(0,ios::beg); // fs << qnbr+1 << endl; // if(!fs.good()) { // DEBUG(cdbg << "Failure on .outgoing/.qnbr\n"); // } // fs.close(); // DEBUG(cdbg << "LServer: qnbr=" << qnbr << endl << article << endl); // sprintf(fn,".outgoing/a%d",qnbr); // fs.open(fn,ios::out); // fs.unsetf(ios::skipws); // fs << article; // fs.close(); return -1; }
