Class PageMgr

java.lang.Object

fc.web.page.PageMgr

public final class PageMgr
extends Object

Manages pages. Pages are found below a web document root directory. Pages are compiled as needed and the resulting class file is loaded/run. If a page is changed, it is automatically recompiled, reloaded and rerun. If the page has a compilation error, that page remains unloaded until the error is fixed.

A new PageMgr should be instantiated for each unique root directory (for example with multiple virtual hosts or users, each having their own root directory).
