Provided Abstracts

Abstract_Plugin

Dream_Encode\WordPress_Plugin_Utils\Abstracts\Abstract_Plugin

Main plugin bootstrap template. Constructs the loader, loads dependencies, sets locale, and wires admin/public hooks.

Must implement:

• get_plugin_slug(): string — returns the plugin slug used as $plugin_name.
• get_version_constant(): string — returns the PHP constant name that holds the plugin version.

Optional overrides:

• get_default_version(): string — fallback version string when the constant is not yet defined (default '1.0.0').
• create_loader(): Plugin_Loader — returns the loader instance; defaults to new Plugin_Loader().
• load_dependencies(): void — require additional files/classes.
• set_locale(): void — instantiate and register the i18n loader.
• define_admin_hooks(): void — register wp-admin actions and filters.
• define_public_hooks(): void — register front-end actions and filters.

Public API:

• run(): void — fires all registered hooks via the loader.
• get_plugin_name(): string
• get_version(): string
• get_loader(): Plugin_Loader

Plugin_Loader

Dream_Encode\WordPress_Plugin_Utils\Loader\Plugin_Loader

Concrete class. Stores and bulk-registers WordPress actions and filters. Can be used directly or subclassed for custom hook-registration behaviour.

Public API:

• add_filter( $hook, $component, $callback, $priority, $accepted_args ): void
• run(): void — calls add_action/add_filter for every registered hook.

Static entry point: activate(): void

Optional overrides (all no-ops by default):

• before_activate(): void

• after_activate(): void

Abstract_Plugin_Deactivator

Dream_Encode\WordPress_Plugin_Utils\Abstracts\Abstract_Plugin_Deactivator

Consistent entry point for register_deactivation_hook.

Object_Data

Dream_Encode\WordPress_Plugin_Utils\Data\Object_Data

Abstract_Data_Migrator

Dream_Encode\WordPress_Plugin_Utils\Abstracts\Abstract_Data_Migrator
