Detailed Description
gnGBKSource is a GenBank sequence file reader.
This class reads and writes the GenBank file format. gnGBKSource is used by gnSourceFactory to read files and should only be used directly when writing out files in GBK file format by calling gnGBKSource::Write ( mySpec, "C:\mySeqFile.gbk");

uint32 gnGBKSource::GetContigID (
const string & name ) const [virtual]
Get a contig index by name.
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.

Get the number of sequence contigs in this source.
Returns:
The number of contigs in this source.
Reimplemented from gnBaseSource .

string gnGBKSource::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 gnGBKSource.cpp .
gnSeqI gnGBKSource::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 gnGBKSource.cpp .
Returns a pointer to the file contig corresponding to contigI or null if none exists.
Reimplemented from gnFileSource .
Definition at line 547 of file gnGBKSource.cpp .
gnGenomeSpec * gnGBKSource::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 127 of file gnGBKSource.h .
boolean gnGBKSource::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 gnGBKSource.cpp .
boolean gnGBKSource::ParseStream (
istream & fin ) [private, 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 .
Definition at line 88 of file gnGBKSource.cpp .
Writes the specified source to a .GBK file named "filename".
Parameters:
source
The source to write out.
filename
The name of the file to write.
Returns:
True if successful, false otherwise.
