bdlb::TransparentEqualTo Struct Reference

#include <bdlb_transparentequalto.h>

Public Types
typedef void	is_transparent
	Type alias indicating this is a transparent comparator.

Public Member Functions
	TransparentEqualTo ()=default
	Create a TransparentEqualTo object.
	TransparentEqualTo (const TransparentEqualTo &original)=default
	~TransparentEqualTo ()=default
	Destroy this object.
TransparentEqualTo &	operator= (const TransparentEqualTo &rhs)=default
template<class LHS , class RHS >
bool	operator() (const LHS &lhs, const RHS &rhs) const

Detailed Description

This struct defines an equality of objects of different types, enabling them for use for heterogeneous comparison in the standard associative containers such as bsl::unordered_map. Note that this class is an empty POD type.

Constructor & Destructor Documentation

TransparentEqualTo() [1/2]

bdlb::TransparentEqualTo::TransparentEqualTo ( )

default

TransparentEqualTo() [2/2]

bdlb::TransparentEqualTo::TransparentEqualTo ( const TransparentEqualTo &  original )

default

Create a TransparentEqualTo object. Note that as TransparentEqualTo is an empty (stateless) type, this operation has no observable effect.

~TransparentEqualTo()

bdlb::TransparentEqualTo::~TransparentEqualTo ( )

default

Member Function Documentation

operator()()

template<class LHS , class RHS >

bool bdlb::TransparentEqualTo::operator() ( const LHS &  lhs, const RHS &  rhs  ) const

inline

Return true if the specified lhs is equal to the specified rhs and false otherwise.

operator=()

TransparentEqualTo & bdlb::TransparentEqualTo::operator= ( const TransparentEqualTo &  rhs )

default

Assign to this object the value of the specified rhs object, and return a reference providing modifiable access to this object. Note that as TransparentEqualTo is an empty (stateless) type, this operation has no observable effect.
