This method has no effect if `other` is this list; otherwise, `other` is left empty. The behavior is undefined unless both `other` and this list are sorted in non‐decreasing order according to the ordering provided by `comparator`, and unless both `other` and this list use the same allocator. == Synopsis Declared in `<bslstl_list.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- template<class COMPARE> void merge( xref:bsl/list-054.adoc[list]& other, COMPARE comparator); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
