Interface CommandLine.IFactory

Enclosing class:

CommandLine

public static interface CommandLine.IFactory

Factory for instantiating classes that are registered declaratively with annotation attributes, like CommandLine.Command.subcommands(), CommandLine.Option.converter(), CommandLine.Parameters.converter() and CommandLine.Command.versionProvider().

The default factory implementation simply creates a new instance of the specified class when create(Class) is invoked.

You may provide a custom implementation of this interface. For example, a custom factory implementation could delegate to a dependency injection container that provides the requested instance.
