- Class Summary
  Class | Description
  --- | ---
  BasicBuilderParameters | An implementation of `BuilderParameters` which handles the parameters of a `ConfigurationBuilder` common to all concrete `Configuration` implementations.
  BasicConfigurationBuilder<T extends ImmutableConfiguration> | An implementation of the `ConfigurationBuilder` interface which is able to create different concrete `ImmutableConfiguration` implementations based on reflection.
  BuilderConfigurationWrapperFactory | A class that allows the creation of configuration objects wrapping a `ConfigurationBuilder`.
  ConfigurationBuilderEvent | A base event class for events generated by a `ConfigurationBuilder`.
  ConfigurationBuilderResultCreatedEvent | A specialized event class which is generated by a `ConfigurationBuilder` when a result configuration has been created.

## Package org.apache.commons.configuration2.builder Description

This package contains the implementations of configuration builder classes used to create new `Configuration` objects.

In Commons Configuration, configuration builders are responsible for the creation and initialization of `Configuration` objects. The typical use case is that a builder is created and configured with initialization parameters defining specific settings for the configuration to be created. The builder can then be stored centrally. Each component requiring access to configuration information queries the builder for its managed `Configuration` and can read or write properties as its pleasure.

### Important note

This package contains a number of interfaces that reflect the initialization parameters available for supported configuration implementations. These interfaces are not intended to be implemented by client code! When new features are added to the represented configuration classes corresponding new methods will be added to them. This can happen even in minor releases.
