Detailed Description

Streams for TBTK output.

The Streams class provides global functions for streaming text output. By default the information is written to stdout and atderr, but the Streams class allows for more customized output. All text output from TBTK is written through the Stream interface, and can therefore be customized through it.

Streams::out

This is the standard output in TBTK. By default, information written to Streams::out is forwarded to std::cout and Streams::log.

Streams::err

This is the error output in TBTK. By default, information written to Streams::err is forwarded to std::err and Streams::log.

Streams::log

This is the logged output in TBTK. By default, the log does not write to anything. However, The two commands

Streams::openLog("LogFilename");

and

Streams::closeLog();

can be used to open and close a log file to which everything is written.

When the log is opened, a time stamp, version number, and git hash for the currently installed version of TBTK is added to the output. Similarly, a time stamp is added when the log is closed. This makes it easy to document the exact setup used to perform a calculation and provides a way for ensuring that the results will be possible to reproduce any time in the future.
