Class Summary

Class	Description
ConfigurationNodeVisitorAdapter	A simple adapter class that simplifies writing custom node visitor implementations.
DefaultConfigurationKey	A simple class that supports creation of and iteration on configuration keys supported by a DefaultExpressionEngine object.
DefaultConfigurationNode	A default implementation of the ConfigurationNode interface.
DefaultConfigurationNode.SubNodes	An internally used helper class for managing a collection of sub nodes.
DefaultExpressionEngine	A default implementation of the ExpressionEngine interface providing the "native"e; expression language for hierarchical configurations.
MergeCombiner	A specialized implementation of the NodeCombiner interface that performs a merge from two passed in node hierarchies.
NodeAddData	A simple data class used by ExpressionEngine to store the results of the prepareAdd() operation.
NodeCombiner	A base class for node combiner implementations.
OverrideCombiner	A concrete combiner implementation that is able to construct an override combination.
TreeUtils	Utility methods.
UnionCombiner	A specialized implementation of the NodeCombiner interface that constructs a union from two passed in node hierarchies.
ViewNode	A specialized node implementation to be used in view configurations.
