bsl::basic_ostringstream::basic_ostringstream

Synopses

Declared in <bslstl_ostringstream.h>

Create a basic_ostringstream object having the same value as the specified original object by moving the contents of original to the newly-created object. Optionally specify the allocator used to supply memory. original is left in a valid but unspecified state.

basic_ostringstream(basic_ostringstream&& original);

Create a basic_ostringstream object. Use the specified initialString indicating the value that will be returned by a call to str prior to any streaming operations performed on this object. Optionally specify a modeBitMask indicating whether the underlying stream-buffer may also be read from (rdbuf is created using modeBitMask | ios_base::out). If modeBitMask is not supplied, rdbuf will be created using ios_base::out. Optionally specify the allocator used to supply memory. If allocator is not supplied, the allocator in initialString is used. initialString is left in a valid but unspecified state.

Create a basic_ostringstream object. Optionally specify a modeBitMask indicating whether the underlying stream-buffer may also be read from (rdbuf is created using modeBitMask | ios_base::out). If modeBitMask is not supplied, rdbuf will be created using ios_base::out. Optionally specify an initialString indicating the value that will be returned by a call to str prior to any streaming operations performed on this object. If initialString is not supplied, str will initially return an empty string. 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.

Create a basic_ostringstream object. 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 have been written to this stream. rdbuf is created using ios_base::out. 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.
