findEquivalent Method

Find an element that compares as equivalent based on some criterion. If multiple elements are equivalent, the specific one returned is unspecified. As an example, consider a SortedArray<ModelState> which uses ModelState.id as its ordering criterion. To find a model by its Id, use sortedArray.findEquivalent((element) => compareStrings(element.id, modelId)) where modelId is an Id64String.

findEquivalent(criterion: (element: T) => number): undefined | T

@returns The first element found that meets the criterion, or undefined if no elements meet the criterion.

@see indexOfEquivalent.

Parameter Type Description
