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.

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.

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.

std::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.

Referenced by Cantera::lastErrorMessage().

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

void logErrors ( )

inline

Prints all of the error messages using writelog.

XML_Node * get_XML_File	(	const std::string &	file,
		int	debug = `0`
	)

Return a pointer to the XML tree for a Cantera input file.

This routine will find the file and read the XML file into an XML tree structure. Then, a pointer will be returned. If the file has already been processed, then just the pointer will be returned.

Parameters

file	String containing the relative or absolute file name
debug	Debug flag

XML_Node * get_XML_from_string ( const std::string & text )

Read a CTI or CTML string and fill up an XML tree.

Return a pointer to the XML tree corresponding to the specified CTI or XML string. If the given string has been processed before, the cached XML tree will be returned. Otherwise, the XML tree will be generated and stored in the cache.

Parameters

text	CTI or CTML string

Returns: Root of the corresponding XML tree

void close_XML_File ( const std::string & file )

Close an XML File.

Close a file that is opened by this application object

Parameters

file	String containing the relative or absolute file name

void writelog ( const std::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 328 of file application.h.

References Application::pMessenger, and Application::Messages::writelog().

Referenced by Application::Messages::logErrors(), Application::warn_deprecated(), and Cantera::writelog().

void writelogendl ( )

inline

Write an endl to the screen and flush output.

Definition at line 333 of file application.h.

References Application::pMessenger, and Application::Messages::writelogendl().

Referenced by Application::warn_deprecated(), and Cantera::writelogendl().

void logerror ( const std::string & msg )

inline

Write an error message and quit.

The default behavior is to write to the standard error stream, and then call exit(). Note that no end-of-line character is appended to the message, and so if one is desired it must be included in the string. Note that this default behavior will terminate the application Cantera is invoked from (MATLAB, Excel, etc.) If this is not desired, then derive a class and reimplement this method.

Parameters

msg	Error message to be written to cerr.

Deprecated:: To be removed after Cantera 2.2

void warn_deprecated	(	const std::string &	method,
		const std::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.

void suppress_deprecation_warnings ( )

inline

Globally disable printing of deprecation warnings.

Used primarily to prevent certain tests from failing.

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

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.
