Member Function Documentation

◆ format_rows()

void Mysql_object_reader::format_rows	(	Item_processing_data *	item_to_process,
		Row_group_dump_task *	row_group
	)

◆ get_id()

uint64 Mysql::Tools::Dump::Mysql_object_reader::get_id ( ) const

inlineoverridevirtual

Returns an application unique ID of this chain element object.

This helps progress watching with multiple parts of chain during all objects processing.

Reimplemented from Mysql::Tools::Dump::Abstract_chain_element.

◆ item_completion_in_child_callback()

void Mysql::Tools::Dump::Mysql_object_reader::item_completion_in_child_callback ( Item_processing_data * item_processed )

inlineoverrideprotectedvirtual

This callback can be requested to be called by child for any object processing.

This will be called when the object processing has completed. Note that this function may be called from multiple threads so all implementations must be thread-safe.

Reimplemented from Mysql::Tools::Dump::Abstract_chain_element.

◆ read_object()

void Mysql_object_reader::read_object ( Item_processing_data * item_to_process )

overridevirtual

Reads information on DB object related to task.

Implements Mysql::Tools::Dump::I_object_reader.

◆ read_table_rows_task()

void Mysql_object_reader::read_table_rows_task	(	Table_rows_dump_task *	table_rows_dump_task,
		Item_processing_data *	item_to_process
	)

private

◆ register_progress_watcher()

void Mysql::Tools::Dump::Mysql_object_reader::register_progress_watcher ( I_progress_watcher * new_progress_watcher )

inlineoverridevirtual

Add new Progress Watcher to report to.

Reimplemented from Mysql::Tools::Dump::Abstract_chain_element.
