# Package org.spongepowered.asm.util.asm

Utilities, abstractions and specialised subclasses used by Mixin for interacting with ASM.

Interface Summary
IAnnotatedElement: Interface for objects which can be annotated since main classes may need to read info from mirror annotations in the AP
IAnnotationHandle: Interface for annotation handle since some classes may need to read info from both ASM `AnnotationNode`s at runtime and mirror annotations in the AP at compile time.

Class Summary
ASM: Utility methods for determining ASM version and other version-specific shenanigans
ClassNodeAdapter: Adapter for ClassNode to access members added after ASM 5
MarkerNode: A label node used as a marker in the bytecode.
MethodNodeEx: MethodNode with some extra convenience functionality
MethodVisitorEx: MethodVisitor with some extra convenience functionality
MixinVerifier: Verifier which handles class info lookups via `ClassInfo`
