Detailed Description

The CopyMeGrid Model; a good start for a CA-based model.

TODO Add your model description here. This model's only right to exist is to be a template for new models. That means its functionality is based on nonsense but it shows how actually useful functionality could be implemented.

Member Typedef Documentation

◆ Base

The type of the Model base class of this derived class.

◆ CellManager

Type of the CellManager to use.

◆ DataGroup

Data type of the group to write model data to, holding datasets.

◆ DataSet

Data type for a dataset.

◆ RuleFunc

Extract the type of the rule function from the CellManager.

This is a function that receives a reference to a cell and returns the new cell state. For more details, check out Utopia::CellManager

Note
Whether the cell state gets applied directly or requires a synchronous update depends on the update mode specified in the cell traits.

Constructor & Destructor Documentation

◆ CopyMeGrid()

template<class ParentModel >
Utopia::Models::CopyMeGrid::CopyMeGrid::CopyMeGrid ( const std::string &  name,
ParentModel &  parent_model,
const DataIO::Config custom_cfg = {} 
)
inline

Construct the CopyMeGrid model.

Parameters
nameName of this model instance; is used to extract the configuration from the parent model and set up a HDFGroup for this instance
parent_modelThe parent model this model instance resides in
custom_cfgA custom configuration to use instead of the one extracted from the parent model using the instance name

Member Function Documentation

◆ calc_some_state_mean()

double Utopia::Models::CopyMeGrid::CopyMeGrid::calc_some_state_mean ( ) const
inlineprivate

Calculate the mean of all cells' some_state.

◆ monitor()

void Utopia::Models::CopyMeGrid::CopyMeGrid::monitor ( )
inline

Monitor model information.

Here, functions and values can be supplied to the monitor that are then available to the frontend. The monitor() function is only called if a certain emit interval has passed; thus, the performance hit is small. With this information, you can then define stop conditions on frontend side, that can stop a simulation once a certain set of conditions is fulfilled.

◆ perform_step()

void Utopia::Models::CopyMeGrid::CopyMeGrid::perform_step ( )
inline

Iterate a single step.

Here you can add a detailed description what exactly happens in a single iteration step

◆ write_data()

void Utopia::Models::CopyMeGrid::CopyMeGrid::write_data ( )
inline

Write data.

This function is called to write out data. The configuration determines the times at which it is invoked. See Utopia::DataIO::Dataset::write
