class libfwbuilder::BackgroundOp

Abstract class BackgroundOp represents operatioin executed in background

Inheritance:

Public Fields

SigC::Signal1<int,int> completed

Public Methods

BackgroundOp()

virtual ~BackgroundOp()

void detach(Pool<BackgroundOp>* p)

virtual pthread_t start_operation(ostream* ) throw(FWException)

These methods are called to initiate and interrupt background operation, respectively

virtual void stop_operation()

bool get_running_flag()

bool get_stop_program_flag()

FWException* get_latest_error()

gint monitor_operation()

This signal handler to be called externally from time to time to ensure that completed signal is issued when task is done.

Protected Fields

FWException* error

Pool<BackgroundOp> * pool

Mutex pool_mutex

Protected Methods

virtual void run_impl(Logger* ) throw(FWException) = 0

Implementation of actual operation.

virtual void operation_completed()

BackgroundOp calls this method from background_thread when run_impl returns.

void set_running_flag()

void clear_running_flag()

virtual void check_stop() throw(FWException)

void clear_stop_program_flag()

User should never manipulate stop flag directly.

void set_stop_program_flag()

Documentation

Abstract class BackgroundOp represents operatioin executed in background

FWException* error

Pool<BackgroundOp> * pool

Mutex pool_mutex

virtual void run_impl(Logger* ) throw(FWException) = 0

Implementation of actual operation.

virtual void operation_completed()

BackgroundOp calls this method from background_thread when run_impl returns.

This method should call BackgroundOp::operation_complted and then perform any specific actions which need to be taken after operation finished. This may be destroying variables, sending report to the Logger, etc.

It should never be called directly.

void set_running_flag()

void clear_running_flag()

virtual void check_stop() throw(FWException)

void clear_stop_program_flag()

User should never manipulate stop flag directly. he should use 'stop_operation' method instead.

void set_stop_program_flag()

BackgroundOp()

virtual ~BackgroundOp()

void detach(Pool<BackgroundOp>* p)

virtual pthread_t start_operation(ostream* ) throw(FWException)

These methods are called to initiate and interrupt background operation, respectively

virtual void stop_operation()

bool get_running_flag()

bool get_stop_program_flag()

FWException* get_latest_error()

gint monitor_operation()

This signal handler to be called externally from time to time to ensure that completed signal is issued when task is done. typical way would be:

bio->start_operation(logger); Gtk::Main::idle.connect(SigC::slot(bio, &BackgroundOp::monitor_operation));

SigC::Signal1<int,int> completed
