Evocosm is finished. More... | |
Evocosm reports its activities through a listener object derived from this abstract class. Some events state that a given event has occurred (e.g., the beginning of a new generation), while others provide text for display.
|
pure virtual |
Ping that fitness testing of an organism begins.
a_organism_number | One-based number of the organism |
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
|
pure virtual |
Ping that processing a generation has ended.
a_organism_number | One-based number of the organism |
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
|
pure virtual |
Ping that processing a generation begins.
a_population | Population before this generation's evolution |
a_iteration | One-based number of the generation begun |
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
|
pure virtual |
Ping that processing a generation has ended.
a_population | Population for which processing has ended |
a_iteration | One-based number of the generation ended |
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
|
pure 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.
a_text | Application-specific text |
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
|
pure 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.
a_text | Application-specific error text |
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
|
pure virtual |
Invoked when an evocosm finishes all processing. This way God can rest on the seventh day.
Implemented in libevocosm::null_listener< OrganismType >, and libevocosm::null_listener< function_solution >.
