com.opencms.template.cache
Class CmsElementCache  

java.lang.Object
  com.opencms.template.cache.CmsElementCache

---

public class CmsElementCache

extends java.lang.Object

This is the starting class for OpenCms element cache. Element cache was implemented for performance issues. The idea is to create a flat hirarchie of elements that can be accessed fast and efficient for the frontend users in the online project. On publishing-time the data in the element cache area will be created or updated. All inefficiant XML-files are changed to the efficient element cache data structure. For createing the content no XML-parsing and DOM-accessing is neccessairy.
