# API

## Delegate(proto, prop)

Creates a delegator instance used to configure using the `prop` on the given
`proto` object. (which is usually a prototype)

## Delegate#method(name)

Allows the given method `name` to be accessed on the host.

## Delegate#getter(name)

Creates a "getter" for the property with the given `name` on the delegated
object.

## Delegate#setter(name)

Creates a "setter" for the property with the given `name` on the delegated
object.

## Delegate#access(name)

Creates an "accessor" (ie: both getter *and* setter) for the property with the
given `name` on the delegated object.

## Delegate#fluent(name)

A unique type of "accessor" that works for a "fluent" API. When called as a
getter, the method returns the expected value. However, if the method is called
with a value, it will return itself so it can be chained. For example:

```js
delegate(proto, 'request')
  .fluent('query')

// getter
var q = request.query();

// setter (chainable)
request
  .query({ a: 1 })
  .query({ b: 2 });
```
