Class Link

java.lang.Object
  wheel.components.Component
      wheel.components.RenderableComponent
          wheel.components.Link

All Implemented Interfaces:: IContainer

public class Link
extends RenderableComponent
implements IContainer
extends RenderableComponent
implements IContainer

Represents a link either to another page inside the application or to an external URL. Examples of valid links:

```
link("FrontPage", "Take me to frontpage");
```
- will finnd a Page class named FrontPage from the basePackageForPages.
```
link("FrontPage?field1=hello&field2=34", "Take me to frontpage");
```
- Same as above but will try to set given parameters to the page-class if fields with thoe names exists. Note that basic type translation works.

link("http://www.dilber.com", "Take me to Dilbert");

```
link("FrontPage.myMethod()", "Call myMethod");
```
- Loads FrontPage, builds it and calls myMethod().
```
link("this.onAction()", "Show some action");
```
- Calls the onAction() method on the current page.
```
link("this.onAction('parameter1')", "Show more action");
```
- Calls onAction-method that takes a String-parameter and passes given value.
```
link("FrontPage:myComponent.foobar()", "Whoa");
```
- Loads FrontPage, builds the page, finds a complex component with id "myComponent" and calls foobar() method on it.
