fetch_schema_component_names_by_criteria()

template<typename T >

bool anonymous_namespace{dictionary_client.cc}::fetch_schema_component_names_by_criteria	(	THD *	thd,
		const dd::Schema *	schema,
		std::vector< dd::String_type > *	names,
		std::function< bool(dd::Raw_record *)> const &	fetch_criteria
	)

HAS_MDL_KEY()

template<typename DDT >

constexpr bool anonymous_namespace{dictionary_client.cc}::HAS_MDL_KEY ( )

constexpr

Compile-time function to determine if a DD type has its own MDL key.

is_locked()

bool anonymous_namespace{dictionary_client.cc}::is_locked	(	THD *	thd,
		const dd::cache::MDL_descriptor &	mdld
	)

Conveniece wrapper for checking if the MDL of an MDL_descriptor is held.

make_mdl_descriptor() [1/2]

template<enum_mdl_type MDL_TYPE>

dd::cache::MDL_descriptor anonymous_namespace{dictionary_client.cc}::make_mdl_descriptor	(	THD *	thd,
		const auto &	object
	)

Wrapper which creates and MDL_descriptor with the correct key and the enum_mdl_type value provided as a template argument.
