java.lang.Object

name.pehl.piriti.restlet.client.UrlBuilder

public class UrlBuilder
extends Object

URL Builder with dedicated support for resources. A resource URL is made up of the following parts:
<protocol>://<host>[:<port>]/[<context>][/<module>][/<version>]<resourcePaths>[?<queryParameter>]

Part	Description	Default	Example
protocol	The protocol. If specified, must not be null / empty.	The protocol from GWT.getHostPageBaseURL()	http, https
host	The hostname. Can include a port. If specified, must not be null / empty.	The host from GWT.getHostPageBaseURL()	127.0.0.1, www.esoves.de:8080
port	The port number. If specified must be something between MIN_PORT and MAX_PORT	The port from GWT.getHostPageBaseURL()	80, 8080
context	The context path. If specified, must not be null / empty. In case the context starts with a '/' there won't be a double '//' in the URL.	The context from GWT.getHostPageBaseURL()	foo, /bar, /
module	Some kind of REST module. If you have many resources you might want to subdivide your resources in different modules like 'admin', 'export', etc. If specified, must not be null / empty.	nothing	admin, common, export
version	In case you meant to include a version identifier in your resources you can specify it with this part. If specified, must not be null / empty.	nothing	r123, v4.2, 56
resourcePaths	The actual resource paths. At least one path must be provided. In case the context starts with a '/' there won't be a double '//' in the URL.	nothing	[user, 0815], [/users, 0815, /groups, 12]
queryParameter	Query parameters. You can specify 0-n values for one parameter. If specified, the name must not be null / empty.	nothing	[foo=[bar], options=[a, b, x]]

Here are some examples of URLs you can build with this class:

• new UrlBuilder().toUrl() → http://localhost/
• new UrlBuilder().toUrl() → http://localhost/
• new UrlBuilder().toUrl() → http://localhost/
• new UrlBuilder().toUrl() → http://localhost/
