Interface PageRenderingCacheService

All Known Implementing Classes:

PageRenderingCacheServiceImpl

public interface PageRenderingCacheService

Manages the Rendering Cache of wiki pages. The cache stores all HTML markups from the wiki page markups. Therefore, it saves much time in rendering markups, especially with a long content page. Generally, its workflow is as follows:

• Open a page, does the page HTML markup exist in the cache?
  • Yes = Reuses this one.
  • No = Renders the page and adds the page HTML markup to the cache.
• Editing a page = Invalidates the page HTML markup in the cache.
