assert
fun <TKey : Comparable<TKey>, TValue> Sequence<TValue>.assertSortedBy(sortOrder: SortOrder = ASCENDING, keySelector: (TValue) -> TKey): SortedSequence<TKey, TValue>
Creates a SortedSequence from this sequence, asserting that elements are sorted by the given key selector.
Example:
val sequence = sequenceOf("az", "by", "cx").assertSortedBy { it.first() }
assertEquals(listOf("az", "by", "cx"), sequence.toList())Content copied to clipboard
Return
A sorted sequence wrapper
Parameters

The type of keys in the sequence, must be comparable
TValue
The type of values in the sequence
sort
The sort order to verify against (default: ASCENDING)
key
Function that extracts the sorting key from each element
