The class Fertility is derived from Action, and determines the agents’ fertility.

Code:
Fertility.h
Fertility.cpp

Attributes

ATTR_FERTILITY_NAME

“Fertility”

action name

ATTR_FERTILITY_MIN_AGE_NAME

“Fertility_min_age”

minimum fertility age (puberty)

ATTR_FERTILITY_MAX_AGE_NAME

“Fertility_max_age”

maximum fertility age (climacterium)

ATTR_FERTILITY_INTERBIRTH_NAME

“Fertility_interbirth”

interbirth interval

Public Methods

constructor

Fertility(SPopulation<T> *pPop, SCellGrid *pCG, std::string sID);
pPop

A pointer to the SPopulation object performing this action.

pCG

A pointer to the SCellGrid object on which the simulation runs.

sID

An ID for this action.

destructor

virtual ~Fertility();

The destructor does nothing.

execute

int execute(int iAgentIndex, float fT);
iAgentIndex

Current agent’s index.

fT

Current simulation step

This method is called for all agents (in parallel).
For each agent the fertility is decided based on age and gender, and the agent’s life state meber variable is changed accordingly.
Females are fertile if their age is in the range defined by m_fFertilityMinAge and m_fFertilityMaxAge, and if the last birth was more than m_fInterbirth years ago.
Males are fertile if they are older than m_fFertilityMinAge.

extractAttributesQDF

virtual int extractAttributesQDF(hid_t hSpeciesGroup);

This method reads the fertility attributes from a QDF file.

writeAttributesQDF

virtual int writeAttributesQDF(hid_t hSpeciesGroup);
hSpeciesGroup

HDF handle for the species group to write to.

This method writes the fertility attributes to the specified group in a QDF file.

tryGetAttributes

virtual int tryGetAttributes(const ModuleComplex *pMC);

Extracts the fertility attributes from the ModuleComplex object.

getMinAge

float getMinAge();

Returns the minimum fertility age.

getMaxAge

float getMaxAge() {return m_fFertilityMaxAge;};

Returns the maximum fertility age.

getInterBirth

float getInterBirth() { return m_fInterbirth;};

Returns the interbirth interval.

isEqual

virtual bool isEqual(Action<T> *pAction, bool bStrict);
pAction

Pointer to an action object to compare with this.

bStrict

Strictness of comparisons (ignored here).

pAction is equal to this, if it is a Fertility object whose attributes match thze ones of this.
