Value‐semantic attribute class characterizing the key data of a hash table.

== Synopsis

Declared in `<bslalg_hashtableanchor.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class HashTableAnchor;
----

== Description

This complex constrained _in_‐_core_ (value‐semantic) attribute class characterizes the key data elements of a hash table. See the  section information on the class attributes. Note that the class invariant is the identically the complex constraint of this component.

This class: * supports a complete set of _value‐semantic_ operations

* except for `bdex` serialization and default construction * is *in‐core* * is *exception‐neutral* (agnostic) * is *alias‐safe* * is `const` *thread‐safe* For terminology see `bsldoc_glossary`.
