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.

References Application::Messages::getErrorCount().

◆ 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.

References Application::Messages::popError().

◆ lastErrorMessage()

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.

Definition at line 224 of file application.h.

References Application::Messages::lastErrorMessage().

◆ 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.

References Application::Messages::getErrors().

◆ 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.

References Application::Messages::logErrors().

◆ get_XML_File()

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

Deprecated:: The XML input format is deprecated and will be removed in Cantera 3.0.

Definition at line 189 of file application.cpp.

References Application::findInputFile(), and Cantera::xml_mutex.

Referenced by Cantera::get_XML_File().

◆ get_XML_from_string()

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

Deprecated:: The XML input format is deprecated and will be removed in Cantera 3.0.

Parameters

file	String containing the relative or absolute file name

Definition at line 246 of file application.cpp.

References Cantera::xml_mutex, and Application::xmlfiles.

Referenced by Cantera::close_XML_File().

◆ writelog()

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
