Functions | |
| template<typename type > | |

| A replacement for standard output stream, with optional logging and other features provided by the class 'outputstream'. More... | |
| outputstream | chomp::homology::scon |
| The console output stream to which one should put all the junk that spoils the log file, like progress indicators. More... | |
| outputstream | chomp::homology::serr |
| A wrapper for the standard error stream. More... | |
| outputstream | chomp::homology::slog |
| The output stream to which one can send messages for logging only. More... | |

| An auxiliary stream which captures sequences of processed data. More... | |
This file contains some useful functions related to the text input/output procedures.
It also contains the definition of some output streams that can be used instead the standard ones (sout, serr) which support logging to a file or suppressing messages to the screen.

| #define ERRORMSG {std::ostringstream error_msg_string; error_msg_string |
The first macro in a pair of macrodefinitions for throwing an error message.
In order to throw an error message of the type std::string, one can type something like the following:
ERRORMSG << "Wrong number: " << n << " instead of 0." << THROW
Note that there is no semicolon at the end. This is important especially in the setting like below:
if (n != 0)
ERRORMSG << .......... << THROW
else
..........
In some cases this pair of macros may probably not work properly, but at the moment I couldn't come up with anything better.
Definition at line 521 of file textfile.h.
| #define MAXTEXTLENGTH 200 |
The maximal length of a phrase read at a time from the input text file by the class textfile.
Definition at line 546 of file textfile.h.
| #define THROW ""; throw error_msg_string. str (). c_str (); } |
The second macro in a pair of macrodefinitions for throwing an error message.
See the description at the ERRORMSG macro.
