stratify()

Build static stratification branches in g (D56 first cut). Rules are a state node so future classifier data changes affect future source items, but branch count is fixed at construction.

Import

import { stratify } from "@graphrefly/ts/composition";

Signature

function stratify(
  g: Graph,
  source: Node<T>,
  rules: readonly StratifyRule<R>[],
  classifier: (rule: R, value: T) => boolean,
  opts: StratifyOptions<R> = {},
): Stratified<T, R>

Parameters

Parameter	Type	Description
g	Graph	Graph that owns the created nodes or projector.
source	Node<T>	Source node that provides graph-visible input.
rules	readonly StratifyRule<R>[]	rules value used by the helper.
classifier	(rule: R, value: T) => boolean	classifier value used by the helper.
opts	StratifyOptions<R>	Options that configure the helper.

Returns

A Stratified<T, R> value.
