4-7: Consider makingvalueoptional instead ofvalue: number | undefined.In TypeScript, an optional property (
value?: number) is not quite the same asvalue: number | undefined, although both allowvalueto be undefined. If the intention is to only occasionally include a node's value, using an optional property could improve clarity.-interface Node { - bitWidth: number; - value: number | undefined; -} +interface Node { + bitWidth: number; + value?: number; +}
14-21: Initialize fields directly without repeating type annotations.You can simplify the constructor/field definitions by inlining the initial values, slightly reducing verbosity and improving readability.
-export default class ContentionPendingData { - private contentionPendingMap: Map<Node, Set<Node>>; - private totalContentions: number; - - constructor() { - this.contentionPendingMap = new Map<Node, Set<Node>>(); - this.totalContentions = 0; - } +export default class ContentionPendingData { + private contentionPendingMap = new Map<Node, Set<Node>>(); + private totalContentions = 0; +}
49-63: Potential concurrency considerations.While the logic for removing a contention is correct in a single-threaded context, be mindful that this code could produce race conditions under concurrent access if parallel threads or tasks attempt to modify the map at the same time. If concurrency is not expected, disregard this note.
69-76: Refactor for efficiency when clearing all contentions for a node.Repeatedly calling
remove()in a loop performs multiple lookups and updates. Consider a direct approach: decreasethis.totalContentionsby the size of the set, clear the set, then deleteourNodefrom the map.removeAllContentionsForNode(ourNode: Node): void { if (!this.contentionPendingMap.has(ourNode)) return; - const contentionsForOurNode = this.contentionPendingMap.get(ourNode)!; - for (const theirNode of contentionsForOurNode) { - this.remove(ourNode, theirNode); - } + const contentionSet = this.contentionPendingMap.get(ourNode)!; + this.totalContentions -= contentionSet.size; + this.contentionPendingMap.delete(ourNode); }
90-101: Apply the same bulk-removal optimization for resolved contentions.Similar to
removeAllContentionsForNode, iterating through every contention and callingremoveIfResolvedmight be less efficient. Consider a more direct approach, collecting all removable nodes first, then removing them in bulk.
110-122: Consider returning a more structured result fromnodes().If there's a use case for quickly searching or grouping these contentions, you might opt for returning a more structured object or direct references, especially if you plan to do further processing on these node pairs downstream.

28-38: ValidatetheirNodebefore adding toourNode's set.If you're working with nodes from various sources, consider verifying that
theirNodeis valid (for instance, ensuring bitWidth is non-negative) before adding it to the collection. This might help guard against invalid data entering your data structure.
78-88: Revisit the resolution logic.The condition
if (ourNode.bitWidth === theirNode.bitWidth && (ourNode.value === theirNode.value || ourNode.value === undefined))means that as soon asourNode.valueis undefined, the node is considered resolved. Verify that this accurately reflects your intended resolution criteria, as it could remove contentions prematurely.
