org.apache.commons.configuration.AbstractConfiguration
Abstract configuration class. Provides basic functionality but does not store any data.

If you want to write your own Configuration class then you should implement only abstract methods from this class. A lot of functionality needed by typical implementations of the Configuration interface is already provided by this base class. Following is a list of features implemented here:
- Data conversion support. The various data types required by the Configuration interface are already handled by this base class. A concrete sub class only needs to provide a generic getProperty() method.
- Support for variable interpolation. Property values containing special variable tokens (like ${var}) will be replaced by their corresponding values.
- Support for string lists. The values of properties to be added to this configuration are checked whether they contain a list delimiter character. If this is the case and if list splitting is enabled, the string is split and multiple values are added for this property. (With the setListDelimiter() method the delimiter character can be specified; per default a comma is used. The setDelimiterParsingDisabled() method can be used to disable list splitting completely.)
- Allows to specify how missing properties are treated. Per default the get methods returning an object will return null if the searched property key is not found (and no default value is provided). With the setThrowExceptionOnMissing() method this behavior can be changed to throw an exception when a requested property cannot be found.
- Basic event support. Whenever this configuration is modified registered event listeners are notified. Refer to the various EVENT_XXX constants to get an impression about which event types are supported.
