Class InputContext

java.lang.Object

org.nuclos.api.context.InputContext

public class InputContext
extends java.lang.Object

InputContext adds support for requesting input from the user. To check if the creator of the request that is executed is able to provide additional information, use isSupported().

There is only one instance of this class (i.e. a singleton). Compared to all-static methods, this works better in a Spring-driven environment.
