47# API
48
49## Delegate(proto, prop)
50
51Creates a delegator instance used to configure using the `prop` on the given
52`proto` object. (which is usually a prototype)
53
54## Delegate#method(name)
55
56Allows the given method `name` to be accessed on the host.
57
58## Delegate#getter(name)
59
60Creates a "getter" for the property with the given `name` on the delegated
61object.
62
63## Delegate#setter(name)
64
65Creates a "setter" for the property with the given `name` on the delegated
66object.
67
68## Delegate#access(name)
69
70Creates an "accessor" (ie: both getter *and* setter) for the property with the
71given `name` on the delegated object.
72
73## Delegate#fluent(name)
74
75A unique type of "accessor" that works for a "fluent" API. When called as a
76getter, the method returns the expected value. However, if the method is called
77with a value, it will return itself so it can be chained. For example:
78
79```js
80delegate(proto, 'request')
81 .fluent('query')
82
83// getter
84var q = request.query();
85
86// setter (chainable)
87request
88 .query({ a: 1 })
89 .query({ b: 2 });
90```
