template<class STREAMBUF>
class bslx::GenericInStream< STREAMBUF >
This class provides input methods to unexternalize values, and C-style arrays of values, of the fundamental integral and floating-point types, as well as bsl::string values, using a byte format documented in the bslx_byteoutstream component. In particular, each get method of this class is guaranteed to read stream data written by the corresponding put method of bslx::GenericOutStream. Note that attempting to read beyond the end of a stream will automatically invalidate the stream. See the bslx package-level documentation for the definition of the BDEX InStream protocol.
