Public Member Functions
	Subfile ()
bool	operator< (const Subfile &other) const
streampos	read_index (istream &read, streampos fpos, Multifile *multfile)
	Reads the index record for the Subfile from the indicated istream.
streampos	write_index (ostream &write, streampos fpos, Multifile *multifile)
	Writes the index record for the Subfile to the indicated ostream.
streampos	write_data (ostream &write, istream *read, streampos fpos)
	Writes the data record for the Subfile to the indicated ostream: the actual contents of the Subfile.
void	rewrite_index_data_start (ostream &write, Multifile *multifile)
	Seeks within the indicate fstream back to the index record and rewrites just the _data_start and _data_length part of the index record.
void	rewrite_index_flags (ostream &write)
	Seeks within the indicate fstream back to the index record and rewrites just the _flags part of the index record.
bool	is_deleted () const
	Returns true if the Subfile indicates it has been deleted (removed from the index), false otherwise.
bool	is_index_invalid () const
	Returns true if there was some problem reading the index record for this Subfile from the Multifile.
bool	is_data_invalid () const
	Returns true if there was some problem reading the data contents of this Subfile, particularly when copying into the Multifile.

Member Function Documentation

bool Multifile::Subfile::is_data_invalid (   )  const [inline]

Returns true if there was some problem reading the data contents of this Subfile, particularly when copying into the Multifile. Definition at line 246 of file multifile.I.

bool Multifile::Subfile::is_deleted (   )  const [inline]

Returns true if the Subfile indicates it has been deleted (removed from the index), false otherwise. This should never be true of Subfiles that currently appear in either the _subfiles or _new_subfiles lists. Definition at line 214 of file multifile.I.

bool Multifile::Subfile::is_index_invalid (   )  const [inline]

Returns true if there was some problem reading the index record for this Subfile from the Multifile. Definition at line 229 of file multifile.I.

bool Multifile::Subfile::operator< (  const Subfile &  other  )  const [inline]

Definition at line 193 of file multifile.I.

streampos Multifile::Subfile::read_index (  istream &  read, streampos  fpos, Multifile *  multfile )

Reads the index record for the Subfile from the indicated istream. Assumes the istream has already been positioned to the indicated stream position, fpos, the start of the index record. Returns the position within the file of the next index record. Definition at line 1492 of file multifile.cxx.

void Multifile::Subfile::rewrite_index_data_start (  ostream &  write, Multifile *  multifile )

Seeks within the indicate fstream back to the index record and rewrites just the _data_start and _data_length part of the index record. Definition at line 1748 of file multifile.cxx.

void Multifile::Subfile::rewrite_index_flags (  ostream &  write  )

Seeks within the indicate fstream back to the index record and rewrites just the _flags part of the index record. Definition at line 1778 of file multifile.cxx. Referenced by Multifile::read_subfile().

streampos Multifile::Subfile::write_data (  ostream &  write, istream *  read, streampos  fpos )

Writes the data record for the Subfile to the indicated ostream: the actual contents of the Subfile. Assumes the istream has already been positioned to the indicated stream position, fpos, the start of the data record, and that this is the effective end of the file. Returns the position within the file of the next data record. The _data_start, _data_length, and _uncompressed_length members are updated by this operation. If the "read" pointer is non-NULL, it is the readable istream of a Multifile in which the Subfile might already be packed. This is used for reading the contents of the Subfile during a repack() operation. Definition at line 1645 of file multifile.cxx.

streampos Multifile::Subfile::write_index (  ostream &  write, streampos  fpos, Multifile *  multifile )

Writes the index record for the Subfile to the indicated ostream. Assumes the istream has already been positioned to the indicated stream position, fpos, the start of the index record, and that this is the effective end of the file. Returns the position within the file of the next index record. The _index_start member is updated by this operation. Definition at line 1567 of file multifile.cxx.
