- All Known Implementing Classes:
ClassInjector.AbstractBase
,ClassInjector.UsingInstrumentation
,ClassInjector.UsingLookup
,ClassInjector.UsingReflection
,ClassInjector.UsingUnsafe
public interface ClassInjector
A class injector is capable of injecting classes into a
ClassLoader
without requiring the class loader to being able to explicitly look up these classes.Important: Byte Buddy does not supply privileges when injecting code. When using a
SecurityManager
, the user of this injector is responsible for providing access to non-public properties.
