# ServiceManager Module Documentation
|
||
|
|
|
||
|
|
## 1. Purpose
|
||
|
|
|
||
|
|
The ServiceManager module implements a service locator pattern, enabling decoupled component communication within the application. It allows components to publish implementations of singleton interfaces (services) that other components can retrieve without direct knowledge of the publisher. The module provides event-driven notification when services are published or unpublished, supporting reactive architectures where consumers need to respond to service availability changes.

| Method | Signature | Description |

|
|
|--------|-----------|-------------|
|
||
|
|
| `Publish<T>` | `void Publish<T>(T item) where T : class` | Publishes a service implementation under its interface type `T`. Throws `ArgumentException` if the type is already published. |
|
||
|
|
| `Publish` | `void Publish(object item, IEnumerable<Type> interfaceList, bool skipPublishedInterfaces)` | Publishes a single object under multiple interface types. If `skipPublishedInterfaces` is `true`, silently skips already-published interfaces; otherwise throws `ArgumentException`. |
|
||
|
|
| `Exists<T>` | `bool Exists<T>() where T : class` | Returns `true` if interface type `T` has been published; otherwise `false`. |
|
||
|
|
| `Exists` | `bool Exists(Type t)` | Non-generic overload. Returns `true` if the specified type has been published; otherwise `false`. |
|
||
|
|
| `Get<T>` | `T Get<T>() where T : class` | Retrieves the published service for interface type `T`. Throws `ArgumentException` if not published. |
|
||
|
|
| `Clear<T>` | `void Clear<T>() where T : class` | Unpublishes the service for interface type `T`. Silently does nothing if the type is not
