Detailed Description

Class to hold global data.

Class Application is the top-level class that stores data that should persist for the duration of the process. The class should not be instantiated directly; instead, it is instantiated as needed by the functions declared here. At most one instance is created, and it is not destroyed until the process terminates.

◆ addError()

void addError	(	const string &	r,
		const string &	msg = `""`
	)

inline

Set an error condition in the application class without throwing an exception.

This routine adds an error message to the end of the stack of errors that Cantera accumulates in the Application class.

Parameters

r	Procedure name which is generating the error condition
msg	Descriptive message of the error condition.

If only one argument is specified, that string is used as the entire message.

Definition at line 209 of file application.h.

◆ getErrorCount()

int getErrorCount ( )

inline

Return the number of errors that have been encountered so far.

Definition at line 214 of file application.h.

◆ popError()

void popError ( )

inline

Discard the last error message.

Cantera saves a stack of exceptions that it has caught in the Application class. This routine eliminates the last exception to be added to that stack.

Definition at line 219 of file application.h.

◆ lastErrorMessage()

string lastErrorMessage ( )

inline

Retrieve the last error message in a string.

This routine will retrieve the last error message and return it in the return string.

Definition at line 224 of file application.h.

◆ getErrors()

void getErrors ( std::ostream & f )

inline

Prints all of the error messages to an ostream.

Write out all of the saved error messages to the ostream f using the function Logger::writelog. Cantera saves a stack of exceptions that it has caught in the Application class. This routine writes out all of the error messages to the ostream and then clears them from internal storage.

Parameters

f	ostream which will receive the error messages

Definition at line 229 of file application.h.

◆ logErrors()

void logErrors ( )

inline

Prints all of the error messages using writelog.

Print all of the error messages using function writelog. Cantera saves a stack of exceptions that it has caught in the Application class. This routine writes out all of the error messages and then clears them from internal storage.

Definition at line 234 of file application.h.

◆ loadExtension()

void loadExtension	(	const string &	extType,
		const string &	name
	)

Load an extension implementing user-defined models.

Parameters

extType	Specifies the interface / language of the extension, for example "python"
name	Specifies the name of the extension. The meaning of this parameter depends on the specific extension interface. For example, for Python extensions, this is the name of the Python module containing the models.

Since: New in Cantera 3.0

Definition at line 378 of file application.cpp.

◆ searchPythonVersions()

void searchPythonVersions ( const string & versions )

Set the versions of Python to try when loading user-defined extensions, in order of preference.

Separate multiple versions with commas, for example "3.11,3.10".

Since: New in Cantera 3.0

Definition at line 429 of file application.cpp.

◆ writelog()

void writelog ( const string & msg )

inline

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

Definition at line 305 of file application.h.

◆ writelogendl()

void writelogendl ( )

inline

Write an endl to the screen and flush output.

Definition at line 310 of file application.h.

◆ warnlog()

void warnlog	(	const string &	warning,
		const string &	msg
	)

inline

Write a warning message to the screen.

Parameters

warning	String specifying type of warning; see Logger::warn()
msg	String to be written to the screen

Definition at line 315 of file application.h.

◆ warn_deprecated()

void warn_deprecated	(	const string &	method,
		const string &	extra = `""`
	)

Print a warning indicating that method is deprecated.

Additional information (removal version, alternatives) can be specified in extra. Deprecation warnings are printed once per method per invocation of the application.

Definition at line 135 of file application.cpp.

◆ suppress_deprecation_warnings()

void suppress_deprecation_warnings ( )

inline

Turns deprecation warnings into exceptions.

Activated within the test suite to make sure that no deprecated methods are being used.

Definition at line 334 of file application.h.

◆ warn()

void warn	(	const string &	warning,
		const string &	method,
		const string &	extra = `""`
	)

Generate a general purpose warning; repeated warnings are not suppressed.

Parameters

warning	Warning type; see Logger::warn()
method	Name of method triggering the warning
extra	Additional information printed for the warning

Definition at line 146 of file application.cpp.

◆ use_legacy_rate_constants()

void use_legacy_rate_constants ( bool legacy = true )

inline

Set definition used for rate constant calculation.

See also: Kinetics::getFwdRateConstants()

If set to false (default value), rate constants of three-body reactions are consistent with conventional definitions (for example Eq. 9.75 in Kee, et al. [15]). If set to true, output for rate constants of three-body reactions is multiplied by third-body concentrations, consistent with Cantera's behavior prior to version 3.0.

Definition at line 383 of file application.h.

◆ legacy_rate_constants_used()

bool legacy_rate_constants_used ( )

inline

Returns true if legacy rate constant definition is used.

Definition at line 388 of file application.h.

◆ setLogger()

void setLogger ( Logger * logwriter )

inline

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

See also: Logger.

Definition at line 393 of file application.h.

◆ thread_complete()

void thread_complete ( )

Delete and free memory allocated per thread in multithreaded applications.

Delete the memory allocated per thread by Cantera. It should be called from within the thread just before the thread terminates. If your version of Cantera has not been specifically compiled for thread safety this function does nothing.
