◆ append_name()

void Opt_hints_key::append_name	(	const THD *	thd,
		String *	str
	)

inlineoverridevirtual

Append key name.

Parameters

thd	pointer to THD object
str	pointer to String object

Implements Opt_hints.

◆ ignore_print()

bool Opt_hints_key::ignore_print ( opt_hints_enum type_arg ) const

inlineoverridevirtual

Ignore printing of the object since parent complex hint has its own printing method.
