A resource is a web resource that is similar in concept to a file resource. It represents a connection and/or permission to access a remote web resource. If a file resource requires a path to a file, the web resource requires a URI to identify the location of the resource.

<resource "http://localhost:9090"/>

To request the value of the resource as a string, get content .

<server root=<H1>Water</H1> port=9090/>
<resource "http://localhost:9090"/>.content

"<h1>Water</h1>"

The following example creates a simple server to serve out the number 42, and uses a 'resource' to get the result as a number using execute . execute will first get the contents as a string, then execute the string to return a Water object.

<server root=42 port=9090/>
<resource "http://localhost:9090/"/>.<execute/>

The following web resource represents a method:

<server <method get_quote arg=req> arg </> port=9090/>
thing.<set remote_get_quote=<resource "http://localhost:9090/"/> />

Calling a remote web resource with arguments has exactly the same structure as calling a local method.

thing.<remote_get_quote arg=100/>

Defining a web resource takes an optional contract. The contract is either a class or method . The contract is used to type-check the arguments before making a remote request.

<method get_quote arg=req=string> arg </>
<server get_quote port=9090/>
thing.<set remote_get_quote=
     <resource "http://localhost:9090/" contract=get_quote/> 
/>
thing.<remote_get_quote arg=6/>
