inline

Read an event object from the stream.

Parameters

[in]	fde	The Format_description_event for deserialization.
[in]	verify_checksum	Verify the checksum of the event_data before
[in]	allocator	It is used to allocate memory for the event data.

Returns

An valid event object if success.

Return values

nullptr

Error

It is convenient for caller to share a Binlog_read_error object between streams.

So Binlog_read_error pointer is defined here. It should be initialized in constructor by caller.
