Command Lifecycle

Command Lifecycle

Commands have three lifecycle methods:

The initialize method (optional)

This method is executed before the interact and execute methods. Its main purpose is to initialize variables used in the rest of the command methods.

The interact method (optional)

This method is executed after initialize and before execute methods. Its purpose is to check if some of the options/arguments are missing and interactively ask the user for those values. This is the last place where you can ask for missing options/arguments. After this command, missing options/arguments will result in an error.

The execute method (required)

This method is executed after interact and initialize methods. It contains the logic you want the command to execute.
