# ToonBoomPlugInManager.dll - PLUG_Services Class Analysis

This document contains reverse engineering analysis of the `PLUG_Services` class hierarchy from `ToonBoomPlugInManager.dll` used in Toon Boom Harmony Premium and Storyboard Pro.

## Overview

The plugin services system in Toon Boom uses a singleton pattern to provide access to various application services. The main classes are:

- **PLUG_Services** - Static class providing access to service interfaces
- **PLUG_ServicesPrivate** - Extended static functionality with setters
- **PLUG_ServicesPrivateImpl** - (alias name, same as PLUG_ManagerImpl)
- **PLUG_ManagerImpl** - Main singleton implementation containing all service pointers
- **PLUG_Manager** - Base class for the manager

## Class: PLUG_Services

### Purpose
Static utility class providing access to all plugin service interfaces. All methods are static.

### Public Static Methods

|---------|--------|-------------|---------------------|
| 0x180005a50 | getActionManager() | AC_Manager* | +0x1A0 (416) |

| 0x180005e00 | getWidgetFactoryRegistry() | PLUG_WidgetFactoryRegistry* | +0x208 (520) |

\* `getExpressionScriptingInterface()` requires `SC_SessionContext` at +0x1C0 to be non-null
\*\* `getInteractiveViewManager()` lazily creates `PLUG_InteractiveViewManagerImpl` if null

### Implementation Pattern

Most getters follow this pattern:
```cpp
Type* PLUG_Services::getXXX() {
    if (g_PLUG_ManagerImpl_instance)
        return g_PLUG_ManagerImpl_instance->m_xxx; // at specific offset
    return nullptr;  // returns 0 if singleton not initialized
}
```

## Analysis Methodology

1. **Function List Analysis**: Extracted all functions matching `*PLUG_Services*` pattern
2. **Decompilation**: Analyzed each getter method to determine offsets in singleton
3. **Constructor Analysis**: Traced `PLUG_ManagerImpl` constructor to map memory layout
4. **Cross-Reference Analysis**: Found setters and initialization points via xrefs to globals
5. **Pattern Recognition**: Identified common getter/setter patterns
6. **Global Identification**: Named and documented global singleton variables
