accessors

Berkeley DB file cursor class.

virtual void Init(void)

Initialize the application.

void x_WalkIndex(bool noMultiFetch, bool noGetData, bool prereadIndex)

virtual void Exit(void)

Cleanup on application exit.

virtual int Run(void)

Run the application.

The NCBI C++ standard methods for dealing with std::string.

virtual const CArgs & GetArgs(void) const

Get parsed command line arguments.

int AppMain(int argc, const char *const *argv, const char *const *envp=0, EAppDiagStream diag=eDS_Default, const char *conf=NcbiEmptyCStr, const string &name=NcbiEmptyString)

Main function (entry point) for the NCBI application.

virtual void SetupArgDescriptions(CArgDescriptions *arg_desc)

Setup the command line argument descriptions.

const CNcbiArguments & GetArguments(void) const

Get the application's cached unprocessed command-line arguments.

@ eInputFile

Name of file (must exist and be readable)

void SetCacheSize(unsigned int cache_size)

Set Berkeley DB memory cache size for the file (default is 256K).

void SetCondition(ECondition cond_from, ECondition cond_to=eNotSet)

Set search condition(type of interval)

void Open(const string &filename, EOpenMode open_mode, bool support_dirty_read=false, unsigned rec_len=0)

Open file with specified access mode.

const string & GetFileName() const

Return file name.

void InitMultiFetch(size_t buffer_size, EMultiFetchMode mfm=eFetchAll)

Init multi-row fetch.

EBDB_ErrCode Fetch(EFetchDirection fdir=eDefault)

Fetch record.

#define LOG_POST(message)

This macro is deprecated and it's strongly recomended to move in all projects (except tests) to macro...

void SetDiagStream(CNcbiOstream *os, bool quick_flush=true, FDiagCleanup cleanup=0, void *cleanup_data=0, const string &stream_name="")

Set diagnostic stream.

void Error(CExceptionArgs_Base &args)

void Info(CExceptionArgs_Base &args)

static void SetLogging(ESwitch on_off_default)

Enable or disable logging of errors from the File API classes.

virtual bool Exists(void) const

Check if directory "dirname" exists.

bool IsDir(EFollowLinks follow=eFollowLinks) const

Check whether a directory entry is a directory.

const string & GetPath(void) const

Get entry path.

uint32_t Uint4

4-byte (32-bit) unsigned integer

IO_PREFIX::ifstream CNcbiIfstream

Portable alias for ifstream.

double Elapsed(void) const

Return time elapsed since first Start() or last Restart() call (in seconds).

@ eStart

Start timer immediately after creating.

Defines the CNcbiApplication and CAppException classes for creating NCBI applications.

Defines command line argument related classes.

Defines unified interface to application:

Defines classes: CDirEntry, CFile, CDir, CSymLink, CMemoryFile, CFileUtil, CFileLock,...

Defines: CTimeFormat - storage class for time format.
