LsaNeighborhoodCondition

class LsaNeighborhoodCondition(reaction: NodeReaction<List<ILsaMolecule>>, molecule: ILsaMolecule, environment: Environment<List<ILsaMolecule>, *>) : LsaStandardCondition

An LSA condition searching an instance of the molecule template in the neighbors of the node.

Constructors

LsaNeighborhoodCondition

constructor(reaction: NodeReaction<List<ILsaMolecule>>, molecule: ILsaMolecule, environment: Environment<List<ILsaMolecule>, *>)

Properties

override val isValid: Observable<Boolean>

The live validity of this condition.

val lsaNode: ILsaNode

The node hosting this condition, as an ILsaNode.

open override val matchingInput: Observable<*>

override val reaction: NodeReaction<List<ILsaMolecule>>

The NodeReaction owning this condition, hosted by targetNode.

val targetNode: Node<List<ILsaMolecule>>

Functions

beforeReactionFires

open fun beforeReactionFires()

Signals that the owning reaction is about to fire. Used to implement conditions latched to changes that occur in-between reaction executions.

override fun cloneCondition(newReaction: Reaction<List<ILsaMolecule>>): Condition<List<ILsaMolecule>>

Creates an equivalent condition owned by newReaction, such as a reaction cloned onto a new node. A condition targeting the host of its reaction targets the host of newReaction, which must then be a Node; a condition targeting any other node keeps its target.

open override fun dispose()

Disposes and releases the resources held by this object.

open override fun filter(matchesList: MutableList<MutableMap<HashString, ITreeNode<*>>>, validNodes: MutableList<ILsaNode>, retrieved: MutableList<MutableMap<ILsaNode, MutableList<ILsaMolecule>>>): Boolean

When this method is called, the condition must filter the current matches and allowed nodes.

getMatchingInput

open override fun getMatchingInput(): Observable<*>

Observable LSA state used to compute matches for this condition.

infix fun Condition<*>.shouldEqual(other: Condition<*>)

open override fun toString(): String
