Simulation.Aivika.Agent

Tested with: GHC 7.6.3

This module introduces basic entities for the agent-based modeling.

Documentation

data Agent

Represents an agent.

Instances

Eq Agent

data AgentState

Represents the agent state.

Instances

Eq AgentState

newAgent :: Simulation Agent

Create an agent.

newState :: Agent -> Simulation AgentState

Create a new state.

newSubstate :: AgentState -> Simulation AgentState

Create a child state.

agentState :: Agent -> Event (Maybe AgentState)

Return the selected downmost active state.

agentStateChanged :: Agent -> Signal (Maybe AgentState)

Return a signal that notifies about every change of the state.

agentStateChanged_ :: Agent -> Signal ()

Return a signal that notifies about every change of the state.

activateState :: AgentState -> Event ()

Select the next downmost active state. The activation is repeated while there is the transition state defined by setStateTransition.

stateAgent :: AgentState -> Agent

Return the corresponded agent.

stateParent :: AgentState -> Maybe AgentState

Return the parent state or Nothing.

addTimeout :: AgentState -> Double -> Event () -> Event ()

Add to the state a timeout handler that will be actuated in the specified time period, while the state remains active.

addTimer :: AgentState -> Event Double -> Event () -> Event ()

Add to the state a timer handler that will be actuated in the specified time period and then repeated again many times, while the state remains active.

setStateActivation :: AgentState -> Event () -> Simulation ()

Set the activation computation for the specified state.

setStateDeactivation :: AgentState -> Event () -> Simulation ()

Set the deactivation computation for the specified state.

setStateTransition :: AgentState -> Event (Maybe AgentState) -> Simulation ()

Set the transition state which will be next and which is used only when activating the state directly with help of activateState. If the state was activated intermediately, when activating directly another state, then this computation is not used.
