# Method Index

This index provides a quick reference to all methods and helper functions in the Pipeline library.

## Creation

| Method           | Description                                            |
| ---------------- | ------------------------------------------------------ |
| `new Standard()` | Creates a new pipeline instance.                       |
| `take()`         | Creates a pipeline from one or more iterables.         |
| `fromArray()`    | Creates a pipeline from an array.                      |
| `fromValues()`   | Creates a pipeline from individual values.             |
| `map()`          | Creates a pipeline from a generator function.          |
| `zip()`          | Combines multiple iterables into a pipeline of tuples. |

## Transformation

| Method      | Description                                          |
| ----------- | ---------------------------------------------------- |
| `map()`     | Transforms elements, with support for generators.    |
| `cast()`    | Transforms elements on a 1-to-1 basis.               |
| `flatten()` | Flattens a nested pipeline by one level.             |
| `unpack()`  | Unpacks array elements as arguments to a callback.   |
| `chunk()`   | Splits the pipeline into chunks of a specified size. |
| `slice()`   | Extracts a portion of the pipeline.                  |

## Filtering

| Method        | Description                                        |
| ------------- | -------------------------------------------------- |
| `filter()`    | Filters elements based on a condition.             |
| `skipWhile()` | Skips elements from the beginning of the pipeline. |

## Aggregation

| Method     | Description                                         |
| ---------- | --------------------------------------------------- |
| `reduce()` | Reduces the pipeline to a single value.             |
| `fold()`   | Reduces the pipeline with a required initial value. |
| `count()`  | Counts the number of elements.                      |
| `min()`    | Finds the minimum value.                            |
| `max()`    | Finds the maximum value.                            |

## Collection

| Method          | Description                                           |
| --------------- | ----------------------------------------------------- |
| `toList()`      | Converts the pipeline to a numerically indexed array. |
| `toAssoc()`     | Converts the pipeline to an associative array.        |
| `getIterator()` | Returns an iterator for the pipeline.                 |
| `each()`        | Iterates over the pipeline for side effects.          |

## Statistics

| Method              | Description                                           |
| ------------------- | ----------------------------------------------------- |
| `finalVariance()`   | Calculates a full set of statistics.                  |
| `runningVariance()` | Calculates statistics without consuming the pipeline. |

## Utility

| Method           | Description                                            |
| ---------------- | ------------------------------------------------------ |
| `reservoir()`    | Selects a random subset of elements.                   |
| `zip()`          | Combines multiple iterables into a pipeline of tuples. |
| `runningCount()` | Counts elements without consuming the pipeline.        |
| `stream()`       | Converts an array-based pipeline to a stream.          |
