Detailed Description

This struct defines a hash operation for different types, enabling them for use for heterogeneous lookup in the standard associative containers such as bsl::unordered_map. Note that this class is an empty POD type.

Constructor & Destructor Documentation

bdlb::TransparentHash::TransparentHash

(

)

Create a TransparentHash object.

bdlb::TransparentHash::TransparentHash

(

const TransparentHash &

original

)

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

bdlb::TransparentHash::~TransparentHash

(

)

Destroy this object.

Member Function Documentation

TransparentHash& bdlb::TransparentHash::operator=

(

const TransparentHash &

rhs

)

Assign to this object the value of the specified rhs object, and return a reference providing modifiable access to this object. Note that as TransparentHash is an empty (stateless) type, this operation has no observable effect.

template<class TYPE >

std::size_t bdlb::TransparentHash::operator()

(

const TYPE &

value

)

const

Return a hash code generated from the contents of the specified value.
