Member Function Documentation

◆ get_id()

virtual uint64 Mysql::Tools::Dump::I_chain_element::get_id ( ) const

pure virtual

Returns an application unique ID of this chain element object.

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

Implemented in Mysql::Tools::Dump::Abstract_chain_element, Mysql::Tools::Dump::Abstract_crawler, Mysql::Tools::Dump::Abstract_progress_watcher, Mysql::Tools::Dump::Compression_lz4_writer, Mysql::Tools::Dump::Compression_zlib_writer, Mysql::Tools::Dump::File_writer, Mysql::Tools::Dump::Mysql_crawler, Mysql::Tools::Dump::Mysql_object_reader, Mysql::Tools::Dump::Mysqldump_tool_chain_maker, Mysql::Tools::Dump::Object_queue, Mysql::Tools::Dump::Sql_formatter, and Mysql::Tools::Dump::Standard_writer.

◆ item_completion_in_child_callback()

virtual void Mysql::Tools::Dump::I_chain_element::item_completion_in_child_callback ( Item_processing_data * item_processed )

protectedpure virtual

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.
