# Class ConfigurationDynaBean

java.lang.Object
java.util.AbstractMap<Object,Object>
org.apache.commons.configuration2.ConfigurationMap
org.apache.commons.configuration2.beanutils.ConfigurationDynaBean

All Implemented Interfaces:
  `Map<Object,Object>`, `org.apache.commons.beanutils.DynaBean`

public class ConfigurationDynaBean extends ConfigurationMap implements org.apache.commons.beanutils.DynaBean
The `ConfigurationDynaBean` dynamically reads and writes configurations properties from a wrapped configuration-collection `Configuration` instance. It also implements a `Map` interface so that it can be used in JSP 2.0 Expression Language expressions.

The `ConfigurationDynaBean` maps nested and mapped properties to the appropriate `Configuration` subset using the `Configuration.subset(java.lang.String)` method. Similarly, indexed properties reference lists of configuration properties using the `ImmutableConfiguration.getList(String)` method. Setting an indexed property is supported, too.

Note: Some of the methods expect that a dot (".") is used as property delimiter for the wrapped configuration. This is true for most of the default configurations. Hierarchical configurations, for which a specific expression engine is set, may cause problems.

Since:
  1.0-rc1
