◆ compare_extra_row_info()

bool binary_log::Rows_event::Extra_row_info::compare_extra_row_info ( const unsigned char *  ndb_info_arg,
int  part_id_arg,
int  source_part_id 
)

Compares the extra_row_info in a Row event, it checks three things.

  1. The m_extra_row_ndb_info pointers. It compares their significant bytes.
  2. Partition_id
  3. source_partition_id
Returns
true all the above variables are same in the event and the one passed in parameter. false Any of the above variable has a different value.
