CommandLineAction class

Represents a sub-command that is part of the CommandLineParser command line. Applications should create subclasses of CommandLineAction corresponding to each action that they want to expose.

The action name should be comprised of lower case words separated by hyphens or colons. The name should include an English verb (e.g. "deploy"). Use a hyphen to separate words (e.g. "upload-docs"). A group of related commands can be prefixed with a colon (e.g. "docs:generate", "docs:deploy", "docs:serve", etc).

Signature:

export declare abstract class CommandLineAction extends CommandLineParameterProvider 

Extends: CommandLineParameterProvider
