org.apache.commons.configuration2.ex.ConfigurationException

An interface for configuration implementations which support registration of event listeners.

Through the methods provided by this interface it is possible to register and remove listeners for different events supported by this library. The event type to be handled by a listener must be provided; the specified event listener must be compatible with this event type. By using generic type parameters, the compiler can check this.
