const IccBuf& readNextRecord (IccFile::ReadMode mode = IccFile::normal,
unsigned long* updateToken = 0)
- mode
- An enumeration, defined in IccFile class, that
indicates the type of read request
- updateToken
- A returned token that is used to identify this unique update request
on a subsequent rewriteRecord, deleteLockedRecord, or unlockRecord method on the file object.
Read the record that follows the current record.

const IccBuf& readPreviousRecord (IccFile::ReadMode mode = IccFile::normal,
unsigned long* updateToken = 0)
- mode
- An enumeration, defined in IccFile class, that
indicates the type of read request.
- updateToken
- See readNextRecord.
Read the record that precedes the current record.

void reset (IccRecordIndex* index,
IccFile::SearchCriterion search = IccFile::gteqToKey)
- index
- A pointer to the IccRecordIndex object that is
being used to select a record in the file.
- search
- An enumeration, defined in IccFile, that indicates
the criterion being used to find a search match. The default is gteqToKey.
Resets the IccFileIterator object to point to the
record identified by the IccRecordIndex object and the
specified search criterion.
