All file source classes are derived from this class. Definition at line 28 of file gnFileSource.h. Constructor & Destructor Documentation gnFileSource::gnFileSource ( ) [inline]   Definition at line 31 of file gnFileSource.h. gnFileSource::gnFileSource ( const gnFileSource & gnfs )   Definition at line 19 of file gnFileSource.cpp. gnFileSource::~gnFileSource ( ) [inline, virtual]   Definition at line 33 of file gnFileSource.h. Member Function Documentation gnFileSource * gnFileSource::Clone ( ) const [pure virtual]   Reimplemented from gnBaseSource. Reimplemented in gnABISource, gnDNXSource, gnFASSource, gnGBKSource, gnRAWSource, and gnSEQSource. void gnFileSource::Close ( ) [virtual]   Closes the file or connection this source is reading from. Exceptions: IOStreamError   if an error occurs closing the file. Reimplemented from gnBaseSource. Definition at line 57 of file gnFileSource.cpp. gnFileContig * gnFileSource::GetFileContig ( const uint32 contigI ) const [pure virtual]   Returns a pointer to the file contig corresponding to contigI or null if none exists. Reimplemented in gnABISource, gnDNXSource, gnFASSource, gnGBKSource, gnRAWSource, and gnSEQSource. const gnFilter * gnFileSource::GetFilter ( ) const [inline, virtual]   Get the filter currently being used to filter unwanted characters out of read sequences. Returns: A pointer to the gnFilter currently in use. Reimplemented from gnBaseSource. Definition at line 67 of file gnFileSource.h. string gnFileSource::GetOpenString ( ) const [inline, virtual]   Get the location of the source that is being used. Returns: The location string describing this source, usually a file name. Reimplemented from gnBaseSource. Definition at line 61 of file gnFileSource.h. void gnFileSource::Open ( ) [virtual]   Opens this source for reading. Exceptions: Will   throw a FileNotOpened exception if the file was not found or was not accessible. Reimplemented from gnBaseSource. Definition at line 49 of file gnFileSource.cpp. Referenced by main(). void gnFileSource::Open ( string openString ) [virtual]   Opens the source given in "openString" for reading. Parameters: openString   The name of the source (file, network URL, or database) to open. Exceptions: Will   throw a FileNotOpened exception if the file was not found or was not accessible. Will propagate a FileUnreadable exception if the file format was invalid. Reimplemented from gnBaseSource. Definition at line 30 of file gnFileSource.cpp. boolean gnFileSource::ParseStream ( istream & fin ) [private, pure virtual]   Reimplemented in gnABISource, gnDNXSource, gnFASSource, gnGBKSource, gnRAWSource, and gnSEQSource. Referenced by Open(). boolean gnFileSource::Read ( const uint64 pos, char * buf, uint32 & bufLen ) [virtual]   Gets raw input from this source. Read will attempt to read "bufLen" bytes starting at "pos" directly from the source. It stores the data in "buf", and returns the actual number of bytes read in bufLen. Read will return false if a serious error occurs. Parameters: pos   The position in the file to start reading. buf   The character array to store data into. len   The number of bytes to read. Returns: True if the operation was successful. Reimplemented from gnBaseSource. Definition at line 64 of file gnFileSource.cpp. Referenced by gnRAWSource::SeqRead(). void gnFileSource::SetFilter ( gnFilter * filter ) [inline, virtual]   Set the filter that will be used to filter unwanted characters out of the sequence data. Parameters: filter   The filter to remove unwanted characters from the sequence. Exceptions: NullPointer   is thrown if the specified filter pointer is null. Reimplemented from gnBaseSource.
