# 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 });
|
||
|
|
```
