Detailed Description

Base virtual class of Flow123D application.

Contains base methods of application for initialization, run and finalization which is used in derived class.

Usage:

class Application : public ApplicationBase {
public:
  Application(int argc, char ** argv); // constructor
protected:
  virtual void run(); // implementation of pure virtual method
  virtual void after_run(); // overriding of parent method
}

Constructor & Destructor Documentation

ApplicationBase::ApplicationBase ( )

protected

Constructor

Construction is done in init method. We need to call virtual methods during construction.

Definition at line 71 of file application_base.cc.

ApplicationBase::~ApplicationBase ( )

protectedvirtual

Destructor.

Definition at line 199 of file application_base.cc.

Member Function Documentation

void ApplicationBase::init	(	int	argc,
		char **	argv
	)

Contains basic structure of application (initialization, run and finalization). Method is call after constructor and allows to call virtual methods.

Definition at line 185 of file application_base.cc.

Here is the caller graph for this function:

virtual void ApplicationBase::parse_cmd_line ( const int  argc, char **  argv  )

protectedpure virtual

Parse command line parameters before Flow123D initialization.

Method must be implemented in derived class.

Implemented in Application.

Here is the caller graph for this function:

int ApplicationBase::petcs_finalize ( )

protected

Finalize PETSC. If finalization failed return nonzero value.

Definition at line 165 of file application_base.cc.

Here is the caller graph for this function:

void ApplicationBase::petsc_initialize ( int  argc, char **  argv  )

protected

Implement printf function for PETSc with support for redirecting. Initialize PETSC.

Definition at line 140 of file application_base.cc.

Here is the caller graph for this function:

virtual void ApplicationBase::run ( )

pure virtual

Run application.

Method must be implemented in derived class.

Implemented in Application.

void ApplicationBase::system_init ( MPI_Comm  comm, const string &  log_filename  )

protected

Read system parameters, open log.

Definition at line 79 of file application_base.cc.

string ApplicationBase::petsc_redirect_file_ =""

protected

Optional file name for output of PETSc parameters. Has to be set in parse_cmd_line()

Definition at line 138 of file application_base.hh.

bool ApplicationBase::signal_handler_off_

protected

Turn off signal handling useful to debug with valgrind.
