bdlb::CaselessStringViewEqualTo Struct Reference

#include <bdlb_caselessstringviewequalto.h>

Detailed Description

This struct defines a case-insensitive equality comparison functor on string views, enabling them for use as keys in the standard unordered associative containers such as bsl::unordered_map and bsl::unordered_set.

Note

Note that this class is an empty POD type.

first_argument_type

typedef bsl::string_view bdlb::CaselessStringViewEqualTo::first_argument_type

is_transparent

typedef void bdlb::CaselessStringViewEqualTo::is_transparent

Type alias indicating this is a transparent hash functor.

Constructor & Destructor Documentation

CaselessStringViewEqualTo() [1/2]

bsl::is_trivially_default_constructible bdlb::CaselessStringViewEqualTo::CaselessStringViewEqualTo ( )

default

Create a CaselessStringViewEqualTo object.

CaselessStringViewEqualTo() [2/2]

bdlb::CaselessStringViewEqualTo::CaselessStringViewEqualTo ( const CaselessStringViewEqualTo &  original )

default

Create a CaselessStringViewEqualTo object.

Note

Note that as CaselessStringViewEqualTo is an empty (stateless) type, this operation has no observable effect.

~CaselessStringViewEqualTo()

bdlb::CaselessStringViewEqualTo::~CaselessStringViewEqualTo ( )

default

Destroy this object.

Member Function Documentation

BSLMF_NESTED_TRAIT_DECLARATION()

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

operator()()

bool bdlb::CaselessStringViewEqualTo::operator() ( bsl::string_view  lhs, bsl::string_view  rhs  ) const

inline

Return true if the specified lhs string view has the same (case insensitive) value as the specified rhs string view, and false otherwise.

operator=()

CaselessStringViewEqualTo & bdlb::CaselessStringViewEqualTo::operator= ( const CaselessStringViewEqualTo &  )

default

Assign to this object the value of the specified rhs object, and return a reference providing modifiable access to this object.

Note

Note that as CaselessStringViewEqualTo is an empty (stateless) type, this operation has no observable effect.
