Detailed Description

Function Documentation

writelog() [1/2]

void writelog

(

const std::string &

msg

)

Write a message to the screen.

The string may be of any length, and may contain end-of-line characters. This method is used throughout Cantera to write log messages. It can also be called by user programs. The advantage of using writelog over writing directly to the standard output is that messages written with writelog will display correctly even when Cantera is used from MATLAB or other application that do not have a standard output stream.

Parameters

msg	c++ string to be written to the screen

setLogger()

void setLogger

(

Logger *

logwriter

)

Install a logger.

Called by the language interfaces to install an appropriate logger. The logger is used for the writelog() function

Parameters

logwriter

Pointer to a logger object

writelog() [2/2]

void Cantera::writelog	(	const std::string &	fmt,
		const Args &...	args
	)

Write a formatted message to the screen.

This function passes its arguments to the fmt library 'format' function to generate a formatted string from a Python-style (curly braces) format string. This method is used throughout Cantera to write log messages. It can also be called by user programs. The advantage of using writelog over writing directly to the standard output is that messages written with writelog will display correctly even when Cantera is used from MATLAB or other application that do not have a standard output stream.

writelogf()

void Cantera::writelogf	(	const char *	fmt,
		const Args &...	args
	)

Write a formatted message to the screen.

Using the printf formatting of C, write a message to the screen with variable values.

Here, we format an internal string with the correct values and then feed it into writelog().

Parameters

fmt	c format string for the following arguments
args	arguments used to interpolate the format string
