:mrdocs:

Create a `basic_stringstream` from a string‐view‐like sequence and mode.

== Synopsis

Declared in `<bslstl_stringstream.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class STRING_VIEW_LIKE_TYPE>
basic_stringstream(
    STRING_VIEW_LIKE_TYPE const& initialString,
    ios_base::openmode modeBitMask);
----

== Description

Use the specified `initialString` (of a type convertible to `basic_string_view<CHAR_TYPE, CHAR_TRAITS>` but not to `const CHAR_TYPE *`) indicating the initial sequence of characters that this stream will access or manipulate. Use the specified `modeBitMask` to indicate whether this stream may be read from, written to, or both. Optionally specify the `allocator` used to supply memory. If `allocator` is not supplied, a default‐constructed object of the (template parameter) `ALLOCATOR` type is used. If the `ALLOCATOR` argument is of type `bsl::allocator` (the default), then `allocator`, if supplied, shall be convertible to `bslma::Allocator *`. If the `ALLOCATOR` argument is of type `bsl::allocator` and `allocator` is not supplied, the currently installed default allocator will be used to supply memory.

== Parameters
