:relfileprefix: ../../../
:mrdocs:

Insert the specified `member` into this `JsonObject` if the key (the `first` element) of the object referred to by `value` does not already exist in this `JsonObject`; otherwise, this method has no effect. Return a `pair` whose `first` member is an iterator referring to the (possibly newly inserted) `value_type` object in this `JsonObject` whose key is equivalent to that of the object to be inserted, and whose `second` member is `true` if a new value was inserted, and `false` if a value having an equivalent key was already present. The behavior is undefined unless `member.first` is valid UTF‐8 (see `bdlde::Utf8Util::isValid`).
