+
+ The BeanFactory is responsible of the creation and
+ lifecycle of beans. It can be a simple implementation or
+ it can be a wrapper of an IoC framework such as
+ Spring (included).
+ Traverser, ItemFilter, ItemComparator and
+ SizeCalculator instances are provided by this class
+ based on the ID. The beanFactory is accessed through a
+ JNDI address (see
+
+ configuration
+
+ ).
+
+ The Traverser is a visitor which walks through the tree
+ and returns a Collection of nodes.
+
+ Included traversers are:
+
+ An ItemFilter implementation is responsible of
+ evaluating whether the given javax.jcr.Item should be
+ included based on the given expression (see filterExp
+ attribute in
+ jcr:nodes
+ ).
+
+ A JEXLItemFilter implementation is provided. It
+ evaluates any javax.jcr.Item based on a JEXL valid
+ expression which returns a Boolean instance. The
+ javax.jcr.Item to be evaluated is added to the
+ JEXLContext under the key "item". A valid JEXL
+ expression would be "item.name.equals('MyNodeName')".
+
+ An ItemComparator implementation is responsible of
+ handling comparison of any javax.jcr.Item based on the
+ given expression.
+
+ A JEXLItemComparator implementation is provided. It
+ compares any javax.jcr.Item based on a JEXL valid
+ expression which returns a comparable instance. The
+ javax.jcr.Item is added to the JEXLContext with the name
+ of "item". A valid JEXL expression would be "item.name".
+
+ A TemplateEngine can be a simple template engine or can + be a wrapper of a powerful template engine such as + Velocity. It writes nodes and properties with the given + template to the given writer. +
++ A SizeCalculator implementation is responsible of + calculating the size that uses a given Node or Property. +
++ JCR tags contains a few Traversers which will help you + on drawing trees. +
++ With this traverser you get a menu with only one + node expanded. +
