String Output Streams ( string_ostream )


An instance O of the data type string$\_$ostream is an C++ostream connected to an internal string buffer, i.e., all output operations or operators applied to O write into this internal buffer. The current value of the buffer is called the contents of O.

#include < LEDA/system/stream.h >


string_ostream O creates an instance O of type string_ostream.


string O.str() returns the current contents of O.

All operations and operators (< <) defined for C++ostreams can be applied to string output streams as well.
