Function Documentation

make_cref()

template<typename Type >

fcppt::reference< Type const > fcppt::make_cref ( Type const &  _ref )

inlinenoexcept

Convenience function to create const references.

make_ref()

template<typename Type >

fcppt::reference< Type > fcppt::make_ref ( Type &  _ref )

inlinenoexcept

Convenience function to create references.

operator!=()

template<typename T >

bool fcppt::operator!= ( fcppt::reference< T > const &  _a, fcppt::reference< T > const &  _b  )

noexcept

Compares two references for inequality.

Compares _a and _b for inequality. Equal to !(_a == _b).

Parameters

_a	The first reference
_b	The second reference

operator<()

template<typename T >

bool fcppt::operator< ( fcppt::reference< T > const &  _a, fcppt::reference< T > const &  _b  )

noexcept

Compares two references lexicographically.

Compares _a and _b lexicographically by comparing the stored pointers via std::less.

Parameters

_a	The first reference
_b	The second reference

operator<<()

template<typename T , typename Ch , typename Traits >

std::basic_ostream< Ch, Traits > & fcppt::operator<<	(	std::basic_ostream< Ch, Traits > &	_stream,
		fcppt::reference< T > const &	_ref
	)

Outputs a reference wrapper to a stream.

operator==()

template<typename T >

bool fcppt::operator== ( fcppt::reference< T > const &  _a, fcppt::reference< T > const &  _b  )

noexcept

Compares two references for equality.

Compares _a and _b for equality. Two references are equal if they refer to the same object.

Parameters

_a	The first reference
_b	The second reference

reference_to_base()

template<typename Base , typename Type >

fcppt::reference< Base > fcppt::reference_to_base ( fcppt::reference< Type > const  _ref )

inlinenoexcept

Converts a reference to a base class.

Template Parameters

Base	Must be a base class of Type

reference_to_const()

template<typename Type >

fcppt::reference< Type const > fcppt::reference_to_const ( fcppt::reference< Type > const  _ref )

inlinenoexcept

Converts a reference to a const reference.

Template Parameters

Type	Must not be const
