virtual void libevocosm::null_listener::ping_fitness_test_begin ( size_t  a_organism_number) [inline, virtual]

Ping that fitness testing of an organism begins.

Parameters:
a_organism_numberOne-based number of the organism

Implements libevocosm::listener.

virtual void libevocosm::null_listener::ping_fitness_test_end ( size_t  a_organism_number) [inline, virtual]

Ping that processing a generation has ended.

Parameters:
a_organism_numberOne-based number of the organism

Implements libevocosm::listener.

virtual void libevocosm::null_listener::ping_generation_begin ( size_t  a_generation_number) [inline, virtual]

Ping that processing a generation begins.

Parameters:
a_generation_numberOne-based number of the generation begun

Implements libevocosm::listener.

virtual void libevocosm::null_listener::ping_generation_end ( size_t  a_generation_number) [inline, virtual]

Ping that processing a generation has ended.

Parameters:
a_generation_numberOne-based number of the generation ended

Implements libevocosm::listener.

virtual void libevocosm::null_listener::ping_population_begin ( size_t  a_population_number) [inline, virtual]

Ping that processing a population begins.

Parameters:
a_population_numberOne-based number of the population begun

Implements libevocosm::listener.

virtual void libevocosm::null_listener::ping_population_end ( size_t  a_population_number) [inline, virtual]

Ping that processing a population has ended.

Parameters:
a_population_numberOne-based number of the population ended

Implements libevocosm::listener.

virtual void libevocosm::null_listener::report ( const std::string &  a_text) [inline, virtual]

This event provide status text specific to a given type of evocosm. The base evocosm class does not call this function. The intention is that this function will be called from classes derived from evocosm to report progress, statistics, or other useful information.

Parameters:
a_textApplication-specific text

Implements libevocosm::listener.

virtual void libevocosm::null_listener::report_error ( const std::string &  a_text) [inline, virtual]

This event provides error text specific to a given type of evocosm. The base evocosm class does not call this function. The intention is that this function will be called from classes derived from evocosm to report problems.

Parameters:
a_textApplication-specific error text

Implements libevocosm::listener.

virtual void libevocosm::null_listener::run_complete ( ) [inline, virtual]

Invoked when an evocosm finishes all processing. This way God can rest on the seventh day.

Implements libevocosm::listener.

virtual void libevocosm::null_listener::yield ( ) [inline, virtual]

Evocosm periodically invokes this function to allow other processes to run. In most cases, this will be some sort of platform-specific sleep function, such as usleep.

Implements libevocosm::listener.
