|
 |
#include <db_cxx.h>
int
DbSequence::set_range(db_seq_t min, db_seq_t max);
int DbSequence::get_range(u_int32_t, db_seq_t *minp, db_seq_t *maxp);
Description: DbSequence::set_range
Configure a sequence range. This call is only effective when the
sequence is being created. The range is limited to a signed 64 bit
integer.
The DbSequence::set_range method may not be called after the
DbSequence::open method is called.
The DbSequence::set_range method
either returns a non-zero error value
or throws an exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
Parameters
- min
- Specifies the minimum value for the sequence.
- max
- Specifies the maximum value for the sequence.
Errors
The DbSequence::set_range method
may fail and throw
DbException,
encapsulating one of the following non-zero errors, or return one of
the following non-zero errors:
- EINVAL
- An
invalid flag value or parameter was specified.
Description: DbSequence::get_range
The DbSequence::get_range method returns the range of values in the sequence.
The DbSequence::get_range method may be called at any time during the life of the
application.
The DbSequence::get_range method
either returns a non-zero error value
or throws an exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
Parameters
- minp
- The DbSequence::get_range method returns the minimum value in minp.
- maxp
- The DbSequence::get_range method returns the maximum value in maxp.
