Examples of PluginRules

org.apache.commons.digester.plugins.PluginRules
A custom digester Rules manager which must be used as the Rules object when using the plugins module functionality.
During parsing, a linked list of PluginCreateRule instances develop, and this list also acts like a stack. The original instance that was set before the Digester started parsing is always at the tail of the list, and the Digester always holds a reference to the instance at the head of the list in the rules member. Initially, this list/stack holds just one instance, ie head and tail are the same object.
When the start of an xml element causes a PluginCreateRule to fire, a new PluginRules instance is created and inserted at the head of the list (ie pushed onto the stack of Rules objects). Digester.getRules() therefore returns this new Rules object, and any custom rules associated with that plugin are added to that instance.
When the end of the xml element is encountered (and therefore the PluginCreateRule end method fires), the stack of Rules objects is popped, so that Digester.getRules returns the previous Rules object. @since 1.6
