Detailed Description

Header file.

This is the .phr or .nhr file. It contains descriptive data for each sequence, including taxonomic information and identifiers for sequence files. The version, title, date, and other summary information is also stored here.

Definition at line 838 of file seqdbfile.hpp.

Member Typedef Documentation

◆ TIndx

typedef CSeqDBAtlas::TIndx CSeqDBHdrFile::TIndx

Type which spans possible file offsets.

Definition at line 841 of file seqdbfile.hpp.

Constructor & Destructor Documentation

◆ CSeqDBHdrFile()

CSeqDBHdrFile::CSeqDBHdrFile	(	CSeqDBAtlas &	atlas,
		const string &	dbname,
		char	prot_nucl
	)

inline

Constructor.

This builds an object which provides access to the header data file for a volume. This file is simply a concatenation of the header data for each object, stored as a Blast-def-line-set objects in binary ASN.1.

Parameters

atlas	The memory management layer object.
dbname	The name of the database volume.
prot_nucl	The sequence data type.
locked	The lock holder object for this thread.

Definition at line 858 of file seqdbfile.hpp.

◆ ~CSeqDBHdrFile()

virtual CSeqDBHdrFile::~CSeqDBHdrFile ( )

inlinevirtual

Destructor.

Definition at line 866 of file seqdbfile.hpp.

Member Function Documentation

◆ GetFileDataPtr()

const char* CSeqDBHdrFile::GetFileDataPtr ( TIndx start ) const

inline

Read part of the file into a buffer.

Copy the sequence data from offsets start to end into the array at buf, which is assumed to already have been allocated. This method assumes the atlas lock is held. If the user will take ownership of the memory region hold, the keep argument should be specified as true.

Parameters

start	The starting offset for the first byte to read.
end	The offset for the first byte after the area to read.
locked	The lock holder object for this thread.

Returns: A pointer into the file data.

Definition at line 907 of file seqdbfile.hpp.

◆ ReadBytes()

void CSeqDBHdrFile::ReadBytes	(	char *	buf,
		TIndx	start,
		TIndx	end
	)		const

inline

Read part of the file into a buffer.

Copy the sequence data from offsets start to end into the array at buf, which is assumed to already have been allocated. This method assumes the atlas lock is held. If the user will take ownership of the memory region hold, the keep argument should be specified as true.

Parameters

buf	The buffer to receive the data.
start	The starting offset for the first byte to read.
end	The offset for the first byte after the area to read.
