Examples of PageFilter

com.day.cq.wcm.api.PageFilter
com.ecyrd.jspwiki.filters.PageFilter
Provides a definition for a page filter. A page filter is a class that can be used to transform the WikiPage content being saved or being loaded at any given time.
Note that the WikiContext.getPage() method always returns the context in which text is rendered, i.e. the original request. Thus the content may actually be different content than what what the wikiContext.getPage() implies! This happens often if you are for example including multiple pages on the same page.
PageFilters must be thread-safe! There is only one instance of each PageFilter per each WikiEngine invocation. If you need to store data persistently, use VariableManager, or WikiContext.
As of 2.5.30, initialize() gains access to the WikiEngine.
org.apache.hadoop.hbase.filter.PageFilter
Implementation of Filter interface that limits results to a specific page size. It terminates scanning once the number of filter-passed rows is > the given page size.
Note that this filter cannot guarantee that the number of results returned to a client are <= page size. This is because the filter is applied separately on different region servers. It does however optimize the scan of individual HRegions by making sure that the page size is never exceeded locally.
