...
delegate(proto, 'request')
.method('acceptsLanguages')
.method('acceptsEncodings')
.method('acceptsCharsets')
.method('accepts')
.method('is')
.access('querystring')
.access('idempotent')
.access('socket')
.access('length')
.access('query')
.access('search')
.access('status')
.access('method')
.access('path')
.access('body')
.access('host')
.access('url')
.getter('subdomains')
.getter('protocol')
.getter('header')
.getter('stale')
.getter('fresh')
.getter('secure')
.getter('ips')
.getter('ip')
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:
delegate(proto, 'request')
.fluent('query')
// getter
var q = request.query();
// setter (chainable)
request
.query({ a: 1 })
.query({ b: 2 });
