Member Function Documentation

BeginStep()

void Hare_Infant::BeginStep ( void  )

overridevirtual

BeginStep for the Hare_Infant.

Tests for mortality. Both standard mortality tests and optional density dependent mortality. NB this differs from all other ALMaSS models in that the farm events do not have any direct impact on any hare stage except this one. I assume that all other stages can run away - seems not to cause a problem with fitting to Illum�

Reimplemented from THare.

ON_BeingFed()

void Hare_Infant::ON_BeingFed

(

double

a_someMilk

)

Get energy from milk given.

The conversion efficiency is pre-calcualted in GetgperKJ so this function is quite simply a conversion from KJ to g
NOTE There are no limits here - the limit to growth has to be by the limited amount of milk supplied - the ultimate limit to this has got to be defined somewhere else (e.g. female forage).

                                               {
    m_TodaysEnergy += a_someMilk;

ON_Dead()

void Hare_Infant::ON_Dead ( void  )

overridevirtual

This hare has been killed.

Do the housekeeping necessary before dying

Reimplemented from THare.

Reimplemented in Hare_Young.

{ st_Dying(); }

OnFarmEvent()

bool Hare_Infant::OnFarmEvent ( FarmToDo  event )

overrideprotectedvirtual

Do we require a response to a farm event.

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).

SetMum()

void Hare_Infant::SetMum ( Hare_Female *  a_af )

Set the mother pointer.

SetWeight()

void Hare_Infant::SetWeight ( double  w )

Set the weight.

This is only used when a hare is born, so no need to have it in the base class

st_Developing()

TTypeOfHareState Hare_Infant::st_Developing ( )

protected

Developmental behaviour for the infant hare.

This code must be called by the EndStep.
To do this we need to add growth and energy requirements. The idea is to grow immediately on milk supply - handled via ON_someMilk()but if there are any other adjustments to be made they ought to be done here, e.g. if energy is needed for movement or thermoregululation. The easiest way to manage things is to use weight as a measure of energy, and convert freely between the two. This means that conversion efficiencies need to be applied to the energy inputs (done in on_BeingFed)

First remove our BMR

Make sure m_TodaysEnergy is zero before we run the risk of getting milk from Mum again during Step tomorrow.

If all is well then mature to become a Hare_Young

Step()

void Hare_Infant::Step ( void  )

overridevirtual

Step for the Hare_Infant.

The step code is the main activity sub-stepfor each time-step. A dead animal will have m_CurrentStateNo set to -1 It is essential that before an animal is killed that it has sent all the necessary messages to others (in this case to its mother).

m_CurrentHState holds the current behavioural state

Reimplemented from THare.

Reimplemented in Hare_Young.
