Do()

bool DK_OCatchCrop::Do ( Farm *  a_farm, LE *  a_field, FarmEvent *  a_ev  )

virtual

The one and only method for a crop management plan. All farm actions go through here.

Called every time something is done to the crop by the farmer in the first instance it is always called with a_ev->todo set to start, but susequently will be called whenever the farmer wants to carry out a new operation.
This method details all the management and relationships between operations necessary to grow and ALMaSS crop - in this case conventional OCatchPeaCrop.

Catch crops in ALMaSS cannot be part of the normal farm plan but are created as part of another crop management. They are therefore dependend on the other crops to set up the starting conditions, hence AddNewEvent is called by the calling crop to create m_startday etc..

Date management control is done by providing pairs of dates as start and stop dates for a management. In this case only harvest can be moved but normally there will be post harvest operations too. These dates are stored using Get and SetMDates

Reimplemented from Crop.
