class | Default_binlog_event_allocator |
class | Binlog_event_data_istream |
Binlog_event_data_istream fetches byte data from Basic_istream and divides them into event_data chunk according to the format. More... | |
class | Binlog_event_object_istream< EVENT_DATA_ISTREAM > |
It reads event_data from an event_data stream and deserialize them to event object. More... | |
class | IBasic_binlog_file_reader |
Interface class that all specializations of template <...> Basic_binlog_file_reader inherit from. More... | |
class | Basic_binlog_file_reader< IFILE, EVENT_DATA_ISTREAM, EVENT_OBJECT_ISTREAM, ALLOCATOR > |
It owns an allocator, a byte stream, an event_data stream and an event object stream. More... | |

) |
Deserialize a binlog event from event_data.
event_data is serialized event object. It is a chunk of data in buffer.
[in] | event_data | The event data used for deserialization. |
[in] | event_data_len | Length of event_data |
[in] | fde | The format_description_event of the event |
[in] | verify_checksum | Verify event_data's checksum if it is true. |
[out] | event | the event object generated. |
Binlog_read_error::SUCCESS | Success |
