Detailed Description

Abstract interface for plugin loading.

This interface defines the contract for loading and unloading plugins. Concrete implementations provide platform-specific loading mechanisms.

Member Function Documentation

get_last_error()

virtual auto kcenon::monitoring::plugin_loader::get_last_error ( ) const -> plugin_load_error

pure virtual

Get the last error that occurred.

Returns

Error code

Implemented in kcenon::monitoring::dynamic_plugin_loader.

get_last_error_message()

virtual auto kcenon::monitoring::plugin_loader::get_last_error_message ( ) const -> std::string

pure virtual

Get detailed error message for the last error.

Returns

Error message string

Implemented in kcenon::monitoring::dynamic_plugin_loader.

get_loaded_plugins()

virtual auto kcenon::monitoring::plugin_loader::get_loaded_plugins ( ) const -> std::vector< std::string >

pure virtual

Get list of loaded plugin names.

Returns

Vector of plugin names

Implemented in kcenon::monitoring::dynamic_plugin_loader.

is_plugin_loaded()

virtual auto kcenon::monitoring::plugin_loader::is_plugin_loaded ( std::string_view plugin_name ) const -> bool

pure virtual

Check if a plugin is currently loaded.

Parameters

plugin_name

Name of the plugin

Returns

True if the plugin is loaded

Implemented in kcenon::monitoring::dynamic_plugin_loader.

load_plugin()

virtual auto kcenon::monitoring::plugin_loader::load_plugin ( std::string_view path ) -> std::unique_ptr< collector_plugin >

pure virtual

Load a plugin from a shared library.

Parameters

path	Path to the plugin library (.so/.dylib/.dll)

Returns

Unique pointer to the loaded plugin, or nullptr on failure

The loader will:

1. Load the shared library
2. Resolve required symbols (create_plugin, etc.)
3. Verify API version compatibility
4. Create the plugin instance
5. Track the plugin for cleanup

On failure, check get_last_error() for details.

Implemented in kcenon::monitoring::dynamic_plugin_loader.

unload_plugin()

virtual auto kcenon::monitoring::plugin_loader::unload_plugin ( std::string_view plugin_name ) -> bool

pure virtual

Unload a previously loaded plugin.

Parameters

plugin_name

Name of the plugin to unload

Returns

True if unloaded successfully

This will:

1. Destroy the plugin instance
2. Unload the shared library
3. Clean up tracking data

The plugin instance must have been destroyed before calling this.

Implemented in kcenon::monitoring::dynamic_plugin_loader.
