class Orienting2D<T, N : ConvexPolygon> @JvmOverloads constructor(val environment: Euclidean2DEnvironmentWithGraph<*, T, N, DefaultEdge>, randomGenerator: RandomGenerator, val node: Node<T>, val knowledgeDegree: Double, minSide: Double = 30.0, maxSide: Double = 60.0) : Orienting<T, Euclidean2DPosition, Euclidean2DTransformation, N, Ellipse>

Basic implementation of a node's OrientingProperty in a 2D space.

Constructors

Orienting2D

@JvmOverloads

constructor(environment: Euclidean2DEnvironmentWithGraph<*, T, N, DefaultEdge>, randomGenerator: RandomGenerator, node: Node<T>, knowledgeDegree: Double, minSide: Double = 30.0, maxSide: Double = 60.0)

Properties

cognitiveMap

open override val cognitiveMap: NavigationGraph<Euclidean2DPosition, Euclidean2DTransformation, Ellipse, DefaultEdge>

The cognitive map of the agent. It's a graph composed of landmarks (elements of the environment easy to remember due to their uniqueness) and spatial relations between them. It's modeled as a NavigationGraph.

environment

open override val environment: Euclidean2DEnvironmentWithGraph<*, T, N, DefaultEdge>

The environment in which the node moves.

knowledgeDegree

open override val knowledgeDegree: Double

The knowledge degree of the agent concerning the environment. This is a Double value in 0, 1 describing the percentage of environment the agent is familiar with prior to the start of the simulation (thus it does not take into account the knowledge the pedestrian will gain during it, namely the volatileMemory).

node

open override val node: Node<T>

randomGenerator

val randomGenerator: RandomGenerator

The simulation RandomGenerator.

volatileMemory

open override val volatileMemory: MutableMap<ConvexShape<Euclidean2DPosition, Euclidean2DTransformation>, Int>

The volatile memory of the agent: it models the ability to remember areas of the environment already visited since the start of the simulation. Each area is paired with the number of visits. Areas are assumed to be represented as ConvexShapes, as in NavigationGraphs.

Functions

cloneOnNewNode

open override fun cloneOnNewNode(node: Node<T>): Orienting2D<T, N>

createLandmarkIn

open override fun createLandmarkIn(area: N): Ellipse

Creates a landmark entirely contained in the given area. If such area contains one or more destinations, the returned landmark must contain at least one of them.

registerVisit

open fun <M : ConvexShape<Euclidean2DPosition, Euclidean2DTransformation>> registerVisit(area: M)

Registers a visit to the provided area in the agent's volatileMemory.

toString

open override fun toString(): String
