Public Functions

explicit HostAPI(CUDASimulation &_agentModel, RandomManager &rng, CUDAScatter &scatter, const AgentOffsetMap &agentOffsets, AgentDataMap &agentData, const unsigned int &streamId, cudaStream_t stream)

Initailises pointers to 0 Stores reference of CUDASimulation


Frees held device memory

HostAgentAPI agent(const std::string &agent_name, const std::string &stateName = ModelData::DEFAULT_STATE)

Returns methods that work on all agents of a certain type currently in a given state

unsigned int getStepCounter() const

Access the current stepCount

Access the current stepCount Sepearate implementation to avoid dependency loop with cuda agent model.


the current step count, 0 indexed unsigned.


the current step count, 0 indexed unsigned.
