Enumeration Type Documentation

Binlog_iterator_service_get_status

enum Binlog_iterator_service_get_status : uint16_t

This enumeration lists the possible return values for the get function.

Enumerator
kBinlogIteratorGetOk	returned when the get operation succeeded. If the get operation succeeds, this also means that the iterator advances.
kBinlogIteratorGetEndOfChanges	returned when there are no more entries to get. The iterator remains open and you can call get on it again. If more content has been created in the meantime, get will get it for you.
kBinlogIteratorGetInsufficientBuffer	returned whenever the get was called with an insufficient buffer. The iterator does not advance and the caller can call get again with a larger buffer.
kBinlogIteratorGetErrorClosed	Returned when there is an unrecoverable error and this iterator has been closed. The caller still needs to deinitialize the iterator.
kBinlogIteratorGetErrorInvalid	returned whenever the iterator context is invalid. The iterator became invalid and therefore it cannot be used successfully from now onwards. I must still be de-initialized to release resources.
kBinlogIteratorGetErrorUnspecified	returned whenever there was an unspecified error attempting to get the next entry. In case of an unspecified error, the caller can retry but there is no guarantee whether the retry is successful or not.

Binlog_iterator_service_init_status

enum Binlog_iterator_service_init_status : uint16_t

Enumerator
kBinlogIteratorInitOk	Iterator was successfully initialized.
kBinlogIteratorIniErrorPurgedGtids	Returned when the required GTIDs have already been purged and therefore the iterator cannot fetch the needed entries. Caller should still call the deinit function on the iterator.
kBinlogIteratorInitErrorLogClosed	Returned when the log is closed and therefore the iterator cannot get the change entries. Caller should still call the deinit function on the iterator.
kBinlogIteratorInitErrorUnspecified	Failure to initialize iterator due to undefined error. Caller should still call the deinit function on the iterator.
