bdlb::CStringEqualTo Struct Reference

#include <bdlb_cstringequalto.h>

Detailed Description

This struct defines a comparison functor on null-terminated character strings, 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.

Constructor & Destructor Documentation

CStringEqualTo()

bdlb::CStringEqualTo::CStringEqualTo ( const CStringEqualTo &  original )

default

Create a CStringEqualTo object.

Note

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

~CStringEqualTo()

bdlb::CStringEqualTo::~CStringEqualTo ( )

default

Destroy this object.

Member Function Documentation

BSLMF_NESTED_TRAIT_DECLARATION()

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

default

Create a CStringEqualTo object.

operator()()

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

inline

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

Precondition

The behavior is undefined unless both lhs and rhs point to null-terminated strings.

operator=()

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

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 CStringEqualTo is an empty (stateless) type, this operation has no observable effect.
