Member Function Documentation

◆ claim_memory_ownership()

void Append_block_log_event::claim_memory_ownership ( bool claim )

overridevirtual

Allow thread to CLAIM or DISCLAIM the ownership of this object depends on the parameter value passed.

Parameters

claim True - claim ownership of the memory False - disclaim ownership of the memory

Reimplemented from Log_event.

Reimplemented in Begin_load_query_log_event.

◆ do_apply_event()

int Append_block_log_event::do_apply_event ( Relay_log_info const * rli )

overrideprivatevirtual

Primitive to apply an event to the database.

This is where the change to the database is made.

Note: The primitive is protected instead of private, since there is a hierarchy of actions to be performed in some cases.

See also: Format_description_log_event::do_apply_event()

Parameters

rli	Pointer to relay log info structure

Return values

0	Event applied successfully
errno	Error code if event application failed
