◆ enumerate_column_statistics()

void Mysql_crawler::enumerate_column_statistics ( const Table table,
Abstract_dump_task dependency 
)
private

◆ enumerate_database_objects()

void Mysql_crawler::enumerate_database_objects ( const Database db)

◆ enumerate_functions()

template<typename TObject >
void Mysql_crawler::enumerate_functions ( const Database db,
std::string  type 
)
private

◆ enumerate_objects()

void Mysql_crawler::enumerate_objects ( )
overridevirtual

Enumerates all objects it can access, gets chains from all registered chain_maker for each object and then execute each chain.

Implements Mysql::Tools::Dump::I_crawler.

◆ enumerate_table_triggers()

void Mysql_crawler::enumerate_table_triggers ( const Table table,
Abstract_dump_task dependency 
)
private

◆ enumerate_tables()

void Mysql_crawler::enumerate_tables ( const Database db)
private

◆ enumerate_users()

void Mysql_crawler::enumerate_users ( )
private

◆ enumerate_views()

void Mysql_crawler::enumerate_views ( const Database db)
private

◆ get_id()

uint64 Mysql::Tools::Dump::Mysql_crawler::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_crawler.

◆ get_version_specific_statement()

std::string Mysql_crawler::get_version_specific_statement ( std::string  create_string,
const std::string &  keyword,
std::string  main_version,
std::string  definer_version 
)
private

Rewrite statement, enclosing it with version specific comment and with DEFINER clause enclosed in version-specific comment.

This function parses any CREATE statement and encloses DEFINER-clause in version-specific comment: input query: CREATE DEFINER=aFUNCTION ... rewritten query: / *!50003 CREATE * / / *!50020 DEFINER=a* / / *!50003 FUNCTION ... * /

◆ item_completion_in_child_callback()

void Mysql::Tools::Dump::Mysql_crawler::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_crawler.

◆ register_progress_watcher()

void Mysql::Tools::Dump::Mysql_crawler::register_progress_watcher ( I_progress_watcher new_progress_watcher)
inlineoverridevirtual

Add new Progress Watcher to report to.

Reimplemented from Mysql::Tools::Dump::Abstract_crawler.
