Insert into this table each such object whose key is not already contained. The (template parameter) type `INPUT_ITERATOR` shall meet the requirements of an input iterator defined in the C++11 standard [24.2.3]providing access to values of a type convertible to `ENTRY`. The behavior is undefined unless `first` and `last` refer to a sequence of valid values where `first` is at a position at or before `last`. == Synopsis Declared in `<bdlc_flathashtable.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- template<class INPUT_ITERATOR> void insert( INPUT_ITERATOR first, INPUT_ITERATOR last); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
