bdlb::TransparentLess Struct Reference

#include <bdlb_transparentless.h>

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

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

Detailed Description

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

Constructor & Destructor Documentation

TransparentLess() [1/2]

bdlb::TransparentLess::TransparentLess ( )

default

TransparentLess() [2/2]

bdlb::TransparentLess::TransparentLess ( const TransparentLess &  original )

default

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

~TransparentLess()

bdlb::TransparentLess::~TransparentLess ( )

default

Member Function Documentation

operator()()

template<class LHS , class RHS >

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

inline

Return true if the specified lhs is less than the specified rhs and false otherwise.

operator=()

TransparentLess & bdlb::TransparentLess::operator= ( const TransparentLess &  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 TransparentLess is an empty (stateless) type, this operation has no observable effect.
