Public member functions:

istringstream members:
(constructor)	Construct an object and optionally initizalize string content.
rdbuf	Get the stringbuf object associated with the stream.
str	Get/set string value.
members inherited from istream:
operator>>	Perform formatted input operation (extraction)
gcount	Get number of characters extracted by last unformatted input operation
get	Extract unformatted data from stream
getline	Get a line from stream
ignore	Extract and discard characters
peek	Peek next character
putback	Put the last character back to stream
read	Read a block of data
readsome	Read a block of data
seekg	Set position of the get pointer
sync	Syncronize stream's buffer with source of characters
tellg	Get position of the get pointer
unget	Make last character got from stream available again
members inherited from ios:
operator void *	Convert stream to pointer.
operator !	Evaluate stream object.
bad	Check if an unrecoverable error has occurred.
clear	Set control states.
copyfmt	Copy formatting information.
eof	Check if End-Of-File has been reached.
exceptions	Get/set the exception mask.
fail	Check if failure has occurred.
fill	Get/set the fill character.
good	Check if stream is good for i/o operations.
imbue	Imbue locale.
narrow	Narrow character.
rdbuf	Get/set the associated streambuf object.

imbue	Imbue locale.
iword	Get reference to a long element of the internal extensible array.
precision	Get/set floating-point decimal presision.
pword	Get reference to a void* element of the internal extensible array.
register_callback	Register event callback function.
setf	Set some format flags.

Description

  istringstream class provides an interface to manipulate strings as if they were input streams.
  The objects of this class mantain internally a pointer to a stringbuf object that can be obtained/modified by calling member rdbuf. This streambuf-derived object stores a sequence of characters (string) that can be obtained/modified by calling member str.
