# Sequence Operations Site [llms.txt](/gatherers4j/llms.txt) --- Gatherers that reorder, combine, or manipulate the sequence of elements. ### Gatherers | Function | Description | |---|---| | [crossWith()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/crosswith/index.md) | Cross every element of the input stream with every element of the given source, emitting them to the output stream as a `Pair`. | | [foldIndexed()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/foldindexed/index.md) | Perform a fold over every element in the input stream along with its index. | | [interleaveWith()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/interleavewith/index.md) | Create a stream of alternating objects from the input stream and the argument source. | | [intersperse()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/intersperse/index.md) | Put the given element between each pair of adjacent elements in the input stream. | | [mapIndexed()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/mapindexed/index.md) | Perform a mapping operation given the element being mapped and its zero-based index. | | [orderByFrequency()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/orderbyfrequency/index.md) | Emit elements in the input stream ordered by the specified frequency. | | [peekIndexed()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/peekindexed/index.md) | Peek at each element of the stream along with its zero-based index. | | [repeat()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/repeat/index.md) | Repeatedly emit the input stream to the output stream a given number of times. | | [repeatInfinitely()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/repeatinfinitely/index.md) | Repeatedly emit the input stream to the output stream, infinitely. | | [reverse()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/reverse/index.md) | Reverse the order of the input stream. | | [rotate()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/rotate/index.md) | Consume the entire stream and emit its elements rotated either left or right `distance` number of spaces. | | [scanIndexed()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/scanindexed/index.md) | Perform a scan over every element in the input stream along with its index. | | [shuffle()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/shuffle/index.md) | Shuffle the input stream into a random order. | | [throttle()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/throttle/index.md) | Limit the number of elements in the stream to some number per period. When the limit is reached, consumption is paused until a new period starts and the count resets. | | [withIndex()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/withindex/index.md) | Maps all elements of the stream as-is along with their 0-based index. | | [zipWith()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/zipwith/index.md) | Creates a stream of `Pair` objects whose values come from the input stream and the source of arguments provided. | | [zipWithNext()](https://tginsberg.github.io/gatherers4j/gatherers/sequence-operations/zipwithnext/index.md) | Creates a stream of `List` objects which contain each two adjacent elements in the input stream. | --- Section pages: - [crossWith()](/gatherers4j/gatherers/sequence-operations/crosswith/): Cross every element of the input stream with every element of the given source, emitting them to the output stream as a `Pair`. - [foldIndexed()](/gatherers4j/gatherers/sequence-operations/foldindexed/): Perform a fold over every element in the input stream along with its index. - [interleaveWith()](/gatherers4j/gatherers/sequence-operations/interleavewith/): Create a stream of alternating objects from the input stream and the argument source. - [intersperse()](/gatherers4j/gatherers/sequence-operations/intersperse/): Put the given element between each pair of adjacent elements in the input stream. - [mapIndexed()](/gatherers4j/gatherers/sequence-operations/mapindexed/): Perform a mapping operation given the element being mapped and its zero-based index. - [orderByFrequency()](/gatherers4j/gatherers/sequence-operations/orderbyfrequency/): Emit elements in the input stream ordered by the specified frequency. - [peekIndexed()](/gatherers4j/gatherers/sequence-operations/peekindexed/): Peek at each element of the stream along with its zero-based index. - [repeat()](/gatherers4j/gatherers/sequence-operations/repeat/): Repeatedly emit the input stream to the output stream a given number of times. - [repeatInfinitely()](/gatherers4j/gatherers/sequence-operations/repeatinfinitely/): Repeatedly emit the input stream to the output stream, infinitely. - [reverse()](/gatherers4j/gatherers/sequence-operations/reverse/): Reverse the order of the input stream. - [rotate()](/gatherers4j/gatherers/sequence-operations/rotate/): Consume the entire stream and emit its elements rotated either left or right `distance` number of spaces. - [scanIndexed()](/gatherers4j/gatherers/sequence-operations/scanindexed/): Perform a scan over every element in the input stream along with its index. - [shuffle()](/gatherers4j/gatherers/sequence-operations/shuffle/): Shuffle the input stream into a random order. - [throttle()](/gatherers4j/gatherers/sequence-operations/throttle/): Limit the number of elements in the stream to some number per period.
