That is, for `(key, value)`, invoke: ` bool visitor(value, key); ` Return the number of elements visited or the negation of that value if visitations stopped because `visitor` returned `false`. `visitor` has read‐only access to each element for duration of each invocation. The behavior is undefined if hash map manipulators are invoked from within `visitor`, as it may lead to a deadlock. == Synopsis Declared in `<bdlcc_stripedunorderedmultimap.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- int visitReadOnly( KEY const& key, xref:BloombergLP/bdlcc/StripedUnorderedMultiMap/ReadOnlyVisitorFunction.adoc[ReadOnlyVisitorFunction] const& visitor) const; ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
