Actions class

A collection of xpm actions for a build configuration or the entire package.

Signature

export declare class Actions

Remarks

This class manages a collection of named actions, each containing one or more commands to be executed. Actions can belong to a package or a build configuration and support template-based definitions with matrix expansion to generate multiple actions from a single template.

The collection always exists, even as empty if no actions are defined.

Action lifecycle phases:

1. Construction: Basic setup with optional inheritance from parent package.
2. Initialisation: Template name expansion without content evaluation.
3. Retrieval: On-demand instantiation when accessed via get().
4. Action Initialisation: Liquid template evaluation and substitution.

This multi-phase approach ensures efficient resource usage by deferring expensive operations until actions are actually needed.
