API

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

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

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

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

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

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 });
