Member Function Documentation

virtual bool qi::OptionalTypeInterface::hasValue ( void * storage )

pure virtual

Return true if the optional has a value, false if not.

TypeKind qi::OptionalTypeInterface::kind ( )

inlineoverridevirtual

Get the kind of the data.

This is used to downcast the TypeInterface object to a specialized interface.

Reimplemented from qi::TypeInterface.

Definition at line 347 of file typeinterface.hpp.

virtual void qi::OptionalTypeInterface::reset ( void ** storage )

pure virtual

Resets the optional value, making the optional empty.

virtual void qi::OptionalTypeInterface::set	(	void **	storage,
		void *	valueStorage
	)

pure virtual

Set the optional value.

virtual AnyReference qi::OptionalTypeInterface::value ( void * storage )

pure virtual

Get the optional value or a default constructed AnyReference if no value is set.

virtual TypeInterface* qi::OptionalTypeInterface::valueType ( )

pure virtual

Get the type of the optional element.
