Detailed Description

This struct defines a hash operation for string views enabling bsl::strings or bsl::string_views to be used as keys in the standard unordered associative containers such as bsl::unordered_map and bsl::unordered_set. Note that this class is an empty POD type.

Constructor & Destructor Documentation

bdlb::CaselessStringViewHash::CaselessStringViewHash

(

)

Create a CaselessStringViewHash object.

bdlb::CaselessStringViewHash::CaselessStringViewHash

(

const CaselessStringViewHash &

original

)

default; Create a CaselessStringViewHash object. Note that as CaselessStringViewHash is an empty (stateless) type, this operation will have no observable effect. Destroy this object.

CaselessStringViewHash& bdlb::CaselessStringViewHash::operator=

(

const CaselessStringViewHash &

rhs

)

default; Assign to this object the value of the specified rhs object, and a return a reference providing modifiable access to this object. Note that as CaselessStringViewHash is an empty (stateless) type, this operation will have no observable effect. Return a hash code generated from the contents of the specified null-terminated argument string, cast to lower case. The behavior is undefined unless argument points to a null-terminated string.
