Member Function Documentation

◆ create()

PFS_engine_table * table_replication_asynchronous_connection_failover::create ( PFS_engine_table_share tbs)
static

Open table function.

Parameters
[in]tbsTable share object

◆ get_row_count()

ha_rows table_replication_asynchronous_connection_failover::get_row_count ( void  )
static

Get the current number of rows read.

Returns
number of rows read.

◆ make_row()

int table_replication_asynchronous_connection_failover::make_row ( uint  index)
private

Stores current row (i.e.index) values for the table into m_row struct members.

This stored data is read later through read_row_values().

Parameters
[in]indexcurrent row position.
Returns
Operation status
Return values
0Success
!=0 Error (error code returned)

◆ read_row_values()

int table_replication_asynchronous_connection_failover::read_row_values ( TABLE table,
unsigned char *  buf,
Field **  fields,
bool  read_all 
)
overrideprotectedvirtual

Read the current row values.

Parameters
[in]tableTable handle
[in]bufrow buffer
[in]fieldsTable fields
[in]read_alltrue if all columns are read.

Implements PFS_engine_table.

◆ reset_position()

void table_replication_asynchronous_connection_failover::reset_position ( void  )
overridevirtual

Reset the cursor position to the beginning of the table.

Implements PFS_engine_table.

◆ rnd_init()

int table_replication_asynchronous_connection_failover::rnd_init ( bool  scan)
overridevirtual

Initialize table for random read or scan.

Parameters
[in]scanif true: Initialize for random scans through rnd_next() if false: Initialize for random reads through rnd_pos()
Returns
Operation status
Return values
0Success
!=0 Error (error code returned)

Reimplemented from PFS_engine_table.

◆ rnd_next()

int table_replication_asynchronous_connection_failover::rnd_next ( void  )
overridevirtual

Read next row via random scan.

Returns
Operation status
Return values
0Success
!=0 Error (error code returned)

Implements PFS_engine_table.

◆ rnd_pos()

int table_replication_asynchronous_connection_failover::rnd_pos ( const void *  pos)
overridevirtual

Read row via random scan from position.

Parameters
[in]posPosition from position() call
Returns
Operation status
Return values
0Success
!=0 Error (error code returned)

Implements PFS_engine_table.
