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 Configuration.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.
