bsl::basic_istringstream::basic_istringstream

Create a basic_istringstream object. Optionally specify a modeBitMask indicating whether the underlying stream-buffer may also be written to (rdbuf is created using modeBitMask | ios_base::in). If modeBitMask is not supplied, rdbuf will be created using ios_base::in. Optionally specify an initialString indicating the sequence of characters from which input will be streamed. If initialString is not supplied, there will not be data to stream (until a subsequent call to the str manipulator). 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. If initialString is passed by MovableRef, it is left in a valid but unspecified state.
