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:

1
2
3
4
5
6
7
8
9
10
delegate(proto, 'request')
.fluent('query')

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

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