Purpose

When creating a browsing view on a folder or a resourcelist, this view mostly consists of links to the displayed resources, actions to execute on these resources or properties of these resources. As these functions are needed again and again in different implementations of ICollectionRenderer orIResourceRenderer, we want to offer standard building blocks that take care of these functions. Because they can be instantiated directly, without calls to the configuration or a factory, their usage is very easy to implement.

Detailed Concept

Readymades can be used just like other htmlb-classes, for instance a TextView component. Differently from other classes within the FlexibleUI, they have a public constructor and can be easily instantiated. You will not find any public methods on these classes - they remain the way they have been instantiated via their constructor. This ensures a straight-forward behavior, because it is - for example - not possible to modify certain parameters of that class at a later point of time thus modifying the result of its rendering process. Their actual coding will be called and executed by the htmlb-framework after the render() methods of the other classes of the FlexibleUI have finished. Keep this in mind, when reseting attributes of classes at the end of their render() methods.
Readymades will throw RuntimeExceptions if the parameter passed into the constructor are not valid! This is done because if they would only fail at the time of the rendering, the FlexibleUI cannot wrap the exceptions into a more decent layout anymore - instead a stack trace might be shown to the user.

Interfaces and Classes

Classes within this package are not depending on each other - there is no hierarchy or interface-cascade. See the javadoc of the classes for details what the classes will render and how they react on the parameters passed.

Configuration

There is no configuration possible

Implementation Notes

Some of the classes will react on the parameterisations used throughout the FlexibleUI. So if the same readymade is used in two different layouts, its result might differ.
