# RoutePattern

## Summary

A parsed route pattern.

Create one with the [`RoutePattern`](/route-pattern/class/RoutePattern/) `parse` method. The constructor is public but takes a parsed
representation that is not part of the public API; prefer `RoutePattern.parse` instead. Use
`source`, `toString()`, `toJSON()`, and [`getRoutePatternCaptures`](/route-pattern/function/getRoutePatternCaptures/) for inspection.

## Signature

```ts
class RoutePattern<source> {
  constructor(parts: RoutePatternParts): RoutePattern<source>

  // Properties
  _parts: RoutePatternParts;
  [brand]: source

  // Accessors
  get source(): string

  // Methods
  toJSON(): RoutePatternJSON
  toString(): string
  parse<source extends string>(source: source): RoutePattern<source>
}

```

## Constructor

Create a new `RoutePattern` from its parsed parts.

The parts are not part of the public API. Use the [`RoutePattern`](/route-pattern/class/RoutePattern/) `parse` method to create a pattern
from a source string.

### Parameters

#### `parts`

The parsed parts of the pattern.

## Properties

### `_parts`

Parsed parts of this pattern. Internal; not part of the public API.

### `[brand]`

## Accessors

### `source`

Normalized string representation of this pattern.

## Methods

### `toJSON(): RoutePatternJSON`

Returns a JSON-serializable object containing each serialized part of this route pattern.



### `toString(): string`

Returns a string representing this route pattern.



### `parse<source extends string>(source: source): RoutePattern<source>`

Create a new `RoutePattern` by parsing a source string.
