inner Zip By Key
fun <TValue2, TValueOut> innerZipByKey(other: SortedKeyValueIteratorProvider<TKey, TValue2>, mergeFn: (TKey, TValue, TValue2) -> TValueOut): SortedKeyValueSequence<TKey, TValueOut>
Performs an inner zip with another sorted sequence.
Example:
val seq1 = sequenceOf(1 to "a", 2 to "b", 2 to "c").assertSorted()
val seq2 = sequenceOf(2 to "x", 2 to "y", 3 to "z").assertSorted()
val result = seq1.innerZipByKey(seq2) { _, v1, v2 -> "$v1$v2" }
assertEquals(
listOf(
2 to "bx",
2 to "cy"
),
result.toList()
)

Return
A new sorted sequence with merged values for keys present in both sequences
Parameters
other
The sequence to zip with
merge Fn
Function that defines how to merge values for matching keys
fun <TValue2> innerZipByKey(other: SortedKeyValueIteratorProvider<TKey, TValue2>): SortedKeyValueSequence<TKey, Pair<TValue, TValue2>>
Performs an inner zip with another sorted sequence using default pairing of values.
Example:
val seq1 = sequenceOf(1 to "a", 2 to "b", 2 to "c").assertSorted()
val seq2 = sequenceOf(2 to "x", 2 to "y", 3 to "z").assertSorted()
val result = seq1.innerZipByKey(seq2)
assertEquals(
listOf(
2 to ("b" to "x"),
2 to ("c" to "y"),
),
result.toList()
)

Return
A new sorted sequence with paired values for keys present in both sequences
Parameters
other
The sequence to zip with
