Detailed Description

An interface to build and use cellular automata.

The Utopia::CellManager and associated constructs allow convenient use of discretizations of physical space into rectangular, hexagonal, or triangular grids.

Typedef Documentation

CellTraits

template<typename StateType , Update update_mode, bool use_def_state_constr = false, typename CellTags = EmptyTag, template< class > class CustomLinkContainers = NoCustomLinks>

using Utopia::CellTraits = typedef EntityTraits<StateType, update_mode, use_def_state_constr, CellTags, CustomLinkContainers>

CellTraits are just another name for Utopia::EntityTraits.

NBFuncID

template<class Grid >

using Utopia::NBFuncID = typedef std::function<IndexContainer(const IndexType)>

Type of the neighborhood calculating function.

Enumeration Type Documentation

GridStructure

enum Utopia::GridStructure

strong

Available grid implementations.

Enumerator
square	A square lattice grid.
triangular	A triangular lattice grid.
hexagonal	A hexagonal lattice grid.

NBMode

enum Utopia::NBMode

strong

Possible neighborhood types; availability depends on choice of grid.

Enumerator
empty	Every entity is utterly alone in the world.
vonNeumann	The vonNeumann neighborhood, i.e. only nearest neighbors.
Moore	The Moore neighborhood, i.e. nearest and next nearest neighbors.
hexagonal	The hexagonal neighbourhood, i.e. the neighbourhood on a hexagonal grid.

Function Documentation

grid_structure_to_string()

std::string Utopia::grid_structure_to_string

(

const GridStructure &

structure

)

Given an GridStructure enum value, return the corresponding string key.

This iterates over the grid_structure_map and returns the first key that matches the given enum value.

nb_mode_to_string()

std::string Utopia::nb_mode_to_string

(

const NBMode &

nb_mode

)

Given an NBMode enum value, return the corresponding string key.

This iterates over the nb_mode_map and returns the first key that matches the given enum value.

    {"triangular",  GridStructure::triangular},
    {"hexagonal",   GridStructure::hexagonal}
}
