BeginStep()

void Hare_Young::BeginStep ( void  )

BeginStep for Hare_Young.

Resets the day's activity counter and checks for default mortalities and potentially extra mortalities. Calculates energy usage for movement based on todays weight

EndStep()

void Hare_Young::EndStep ( void  )

overridevirtual

EndStep code for Hare_Young.

NB development must be called here because they hares may be still getting milk from Mum.
In EndStep, the home-range centre peg gravitates a little way towards the daily activity area for today.

Reimplemented from Hare_Infant.

Init()

void Hare_Young::Init

(

double

p_weight

Object initiation.

                                     {
    m_Type = hob_Young;
    m_weight = p_weight;
    m_Age = 11; // By definition we are 11 days old today
}

References hob_Young, THare::m_Age, THare::m_Type, and THare::m_weight.

ON_Dead()

void Hare_Young::ON_Dead ( void  )

overridevirtual

This hare has been killed.

Housekeeping for removal of the object, lets Mum know if there is a Mum

Reimplemented from Hare_Infant.

{ st_Dying(); }

References THare::st_Dying().

Referenced by BeginStep(), EndStep(), and OnFarmEvent().

OnFarmEvent()

bool Hare_Young::OnFarmEvent ( FarmToDo  event )

overrideprotectedvirtual

Response to farm actions.

Checks to see if any nasty farm event has caused the death of the infant.
Currently there is only one response to those events where death is possible. However, this may not always be the case so the code is structured as for the other ALMaSS animals (i.e. it could be a bit easier to overview if it were written differently).

Young foraging.

The amount of time spent on this is dependent upon age. They can take in food up to a proportion of their needs increasing with age. This gives us a little problem because we don't explicitly define their needs. We assume therefore that the milk supply is maximal and that the the time available is all day - but that the max solid food intake possible is defined by age, following the data from Hacklander - this gives no flexibility in the proportion of max food but will cause differential growth w.r.t. milk supply.

    // Given the time we have then we need to feed, which will return an energy
    // Value obtained.

Maturation to Hare_Juvenile.

Young 'matures' to become a Hare_Juvenile.

This creats a Hare_Juvenile object via a call to create objects, then sets the flag for destruction of this object.
