stringstream::str

public member function

string str ( ) const;
void str ( const string & s );

Get/set the associated string object

The first version returns a copy of the string object currently associated with the string stream buffer.

The second syntax copies the content of string s to the string object associated with the string stream buffer.

The function effectivelly calls rdbuf()->str().

Notice that setting a new string does not clear the error flags currently set in the stream object unless the member function clear is explicitly called.

Parameters

s: String object whose content is to be copied to the string stream buffer.

Return Value

The first version returns a copy of the string object currently associated with the stream buffer.
