Detailed Description
Controlling input and output for std::string.
This class supports reading from and writing to objects of type std::basic_string, using the inherited functions from std::basic_iostream. To control the associated sequence, an instance of std::basic_stringbuf is used, which this page refers to as sb.
Constructor & Destructor Documentation
| std::basic_stringstream::basic_stringstream | ( | ios_base::openmode | __m = ios_base::out | ios_base::in | ) | [inline, explicit] |
Default constructor starts with an empty string buffer.
- Parameters:
-
mode Whether the buffer can read, or write, or both.
Initializes sb using mode, and passes &sb to the base class initializer. Does not allocate any buffer.
That's a lie. We initialize the base class with NULL, because the string class does its own memory management.
| std::basic_stringstream::basic_stringstream | ( | const __string_type & | __str, |
| ios_base::openmode | __m = ios_base::out | ios_base::in |
||
| ) | [inline, explicit] |
Starts with an existing string buffer.
- Parameters:
-
str A string to copy as a starting buffer. mode Whether the buffer can read, or write, or both.
Initializes sb using str and mode, and passes &sb to the base class initializer.
That's a lie. We initialize the base class with NULL, because the string class does its own memory management.

Member Function Documentation
| __stringbuf_type* std::basic_stringstream::rdbuf | ( | ) | const [inline] |
Accessing the underlying buffer.
- Returns:
- The current basic_stringbuf buffer.
This hides both signatures of std::basic_ios::rdbuf().
| __string_type std::basic_stringstream::str | ( | ) | const [inline] |
Copying out the string buffer.

References std::basic_stringbuf::str().
| void std::basic_stringstream::str | ( | const __string_type & | __s | ) | [inline] |
Setting a new buffer.
- Parameters:
-
s The string to use as a new sequence.
Calls rdbuf()->str(s).
