Declared in `<bdlc_compactedarray.h>`

    std::ptrdiff_t offset);
----

== Description

The returned iterator, `it`, referencing a `CompactedArray` `array`, remains valid as long as `0 <= it ‐ array.begin() <= array.length()`. The behavior is undefined unless `CompactedArray_ConstIterator() != iterator` and `0 <= iterator ‐ array.begin() ‐ offset <= array.length()`.

== Return Value

iterator at the negated specified offset from `iterator`
