Detailed Description

This struct defines an ordering on null-terminated character strings, enabling them for use as keys in the standard associative containers such as bsl::map and bsl::set. Note that this class is an empty POD type.

first_argument_type

Constructor & Destructor Documentation

CStringLess() [1/2]

bdlb::CStringLess::CStringLess ( )

default

CStringLess() [2/2]

bdlb::CStringLess::CStringLess ( const CStringLess &  original )

default

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

~CStringLess()

bdlb::CStringLess::~CStringLess ( )

default

Member Function Documentation

BSLMF_NESTED_TRAIT_DECLARATION() [1/2]

bdlb::CStringLess::BSLMF_NESTED_TRAIT_DECLARATION	(	CStringLess	,
		bsl::is_trivially_copyable
	)

BSLMF_NESTED_TRAIT_DECLARATION() [2/2]

bdlb::CStringLess::BSLMF_NESTED_TRAIT_DECLARATION	(	CStringLess	,
		bsl::is_trivially_default_constructible
	)

operator()()

bool bdlb::CStringLess::operator() ( const char *  lhs, const char *  rhs  ) const

inline

Return true if the specified lhs string is lexicographically ordered before the specified rhs string, and false otherwise. The behavior is undefined unless both lhs and rhs point to null-terminated strings.

operator=()

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