This class reads and writes the DNAStar SEQ file format. gnSEQSource is used by gnSourceFactory to read files and should only be used directly.when writing out files in SEQ file format by calling gnSEQSource::Write( mySpec, "C:\mySeqFile.seq"); Definition at line 35 of file gnSEQSource.h.

If the source does not contain a contig by the specified name GetContigID returns UINT32_MAX. Parameters: name   The name of the contig to look for. Returns: The index of the named contig or UINT32_MAX. Reimplemented from gnBaseSource. Definition at line 60 of file gnSEQSource.cpp. uint32 gnSEQSource::GetContigListLength ( ) const [inline, virtual]   Get the number of sequence contigs in this source. Returns: The number of contigs in this source. Reimplemented from gnBaseSource. Definition at line 108 of file gnSEQSource.h. string gnSEQSource::GetContigName ( const uint32 i ) const [virtual]   Get the name of the specified contig. Returns an empty string if the specified contig is out of range. Parameters: i   The index of the contig or ALL_CONTIGS. Returns: The name of the contig or an empty string. Reimplemented from gnBaseSource. Definition at line 69 of file gnSEQSource.cpp. gnSeqI gnSEQSource::GetContigSeqLength ( const uint32 i ) const [virtual]   Get the total number of base pairs in the specified contig. Parameters: i   The index of the contig or ALL_CONTIGS. Returns: The length in base pairs of the specified contig. Reimplemented from gnBaseSource. Definition at line 77 of file gnSEQSource.cpp. gnFileContig * gnSEQSource::GetFileContig ( const uint32 contigI ) const [virtual]   Returns a pointer to the file contig corresponding to contigI or null if none exists. Reimplemented from gnFileSource. Definition at line 329 of file gnSEQSource.cpp. gnGenomeSpec * gnSEQSource::GetSpec ( ) const [inline, virtual]   Get the annotated sequence data as a gnGenomeSpec. GetSpec returns a gnGenomeSpec which contains the sequence, header, and feature data contained by this source. Returns: The annotated sequence data. Reimplemented from gnBaseSource. Definition at line 121 of file gnSEQSource.h. boolean gnSEQSource::HasContig ( const string & name ) const [virtual]   Looks for a contig by name. Returns true if it finds the contig, otherwise false. Parameters: name   The name of the contig to look for. Returns: True if the named contig exists, false otherwise. Reimplemented from gnBaseSource. Definition at line 51 of file gnSEQSource.cpp. boolean gnSEQSource::ParseStream ( istream & fin ) [private, virtual]   Reimplemented from gnFileSource. Definition at line 336 of file gnSEQSource.cpp. boolean gnSEQSource::SeqRead ( const gnSeqI start, char * buf, uint32 & bufLen, const uint32 contigI = ALL_CONTIGS ) [virtual]   Gets sequence data from this source. SeqRead will attempt to read "bufLen" base pairs starting at "start", an offset into the sequence. Reading inside a specific contig can be accomplished by supplying the "contigI" parameter with a valid contig index. SeqRead stores the sequence data in "buf" and returns the actual number of bases read in "bufLen". SeqRead will return false if a serious error occurs. Parameters: start   The base pair to start reading at. buf   The character array to store base pairs into. len   The number of base pairs to read. contigI   The index of the contig to read or ALL_CONTIGS by default. Returns: True if the operation was successful. Reimplemented from gnBaseSource.
