Member Function Documentation

◆ create()

PFS_engine_table * table_rpl_async_connection_failover_managed::create ( PFS_engine_table_share * tbs )

static

Open table function.

Parameters

[in] tbs Table share object

◆ get_row_count()

ha_rows table_rpl_async_connection_failover_managed::get_row_count ( )

static

Get the current number of rows read.

Returns: number of rows read.

◆ make_row()

int table_rpl_async_connection_failover_managed::make_row ( uint index )

private

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

Returns: Operation status

Return values

0	Success
!=	0 Error (error code returned)

◆ read_row_values()

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

overrideprotectedvirtual

Read the current row values.

Parameters

[in]	table	Table handle
[in]	buf	row buffer
[in]	fields	Table fields
[in]	read_all	true if all columns are read.

Returns: Operation status

Return values

0	Success
!=	0 Error (error code returned)

configuration

Implements PFS_engine_table.

◆ reset_position()

void table_rpl_async_connection_failover_managed::reset_position ( )

overridevirtual

Reset the cursor position to the beginning of the table.

Implements PFS_engine_table.

◆ rnd_init()

int table_rpl_async_connection_failover_managed::rnd_init ( bool scan )

overridevirtual

Initialize table for random read or scan.

Parameters

[in] scan if true: Initialize for random scans through rnd_next() if false: Initialize for random reads through rnd_pos()

Returns: Operation status

Return values

0	Success
!=	0 Error (error code returned)

Reimplemented from PFS_engine_table.

◆ rnd_next()

int table_rpl_async_connection_failover_managed::rnd_next ( )

overridevirtual

◆ rnd_pos()

int table_rpl_async_connection_failover_managed::rnd_pos ( const void * pos )

overridevirtual

Read row via random scan from position.

Parameters

[in] pos Position from position() call

Returns: Operation status

Return values

0	Success
!=	0 Error (error code returned)

Implements PFS_engine_table.
