- All Implemented Interfaces:
- IPageLoader
- public class PageLoader
- extends Object
- implements IPageLoader
Runs the process of building the component hierarchy for an entire page.
This class is not threadsafe; however, PageSource
creates a new instance of it for each page to be loaded, which bypasses
multithreading issues.
