MulleObjCLoader

Class that manages class and category dependencies, ensuring proper initialization order across frameworks.

Base Class

NSObject

Methods

Dependency Management

• +dependencies - Returns array of dependencies
• +loadversion - Returns version requirements

Load Control

• +load - Performs loading
• +unload - Performs unloading

Usage Example

// Define framework loader
@interface MyFrameworkLoader : MulleObjCLoader
@end

@implementation MyFrameworkLoader

+ (struct _mulle_objc_dependency *) dependencies
{
    static struct _mulle_objc_dependency   dependencies[] =
    {
       { @"Foundation", MULLE_OBJC_NO_VERSION, MULLE_OBJC_NO_VERSION },
       { NULL, MULLE_OBJC_NO_VERSION, MULLE_OBJC_NO_VERSION }
    };
    return dependencies;
}

@end

// Define category loader
@interface NSString_MyAdditions_Loader : MulleObjCLoader
@end

@implementation NSString_MyAdditions_Loader

+ (struct _mulle_objc_dependency *) dependencies
{
    static struct _mulle_objc_dependency   dependencies[] =
    {
       { @"NSString", MULLE_OBJC_NO_VERSION, MULLE_OBJC_NO_VERSION },
       { NULL, MULLE_OBJC_NO_VERSION, MULLE_OBJC_NO_VERSION }
    };
    return dependencies;
}

@end

Important Notes

1. Dependency Management
   • Order dependencies properly
   • Specify version requirements
   • Document dependencies
2. Load Management
   • Handle load failures
   • Clean up resources
   • Validate dependencies
3. Performance
   • Minimize load time
   • Optimize dependencies
   • Cache when possible
4. Thread Safety
   • Load-time synchronization
   • Resource protection
   • State management
5. Error Handling
   • Load failures
   • Version mismatches
   • Missing dependencies
