If an exception is thrown, `*this` is unaffected. Throw `std::length_error` if `size() == max_size()`. This method requires that the (template parameter) type `VALUE_TYPE` be `copy‐constructible` (see {Requirements on `VALUE_TYPE`}). == Synopsis Declared in `<bslstl_vector.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- void push_back(long long const& value); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
