## 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
