Classes
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...

binlog_event_deserialize()

Binlog_read_error::Error_type binlog_event_deserialize	(	const unsigned char *	event_data,
		unsigned int	event_data_len,
		const Format_description_event *	fde,
		bool	verify_checksum,
		Log_event **	event
	)

Deserialize a binlog event from event_data.

event_data is serialized event object. It is a chunk of data in buffer.

Parameters

[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.

Return values

Binlog_read_error::SUCCESS	Success
Other	than Binlog_read_error::SUCCESS Error
