UsingUnsafeInjection

protected UsingUnsafeInjection(Object accessor,
                               Method findLoadedClass,
                               Method defineClass,
                               Method getPackage,
                               Method definePackage,
                               Method getClassLoadingLock)

Creates a new class loading injection dispatcher using an unsafe injected dispatcher.

Parameters:

accessor - An instance of the accessor class that is required for using it's intentionally non-static methods.

findLoadedClass - An instance of ClassLoader.findLoadedClass(String).

defineClass - An instance of ClassLoader.defineClass(String, byte[], int, int, ProtectionDomain).

getPackage - An instance of ClassLoader.getPackage(String) or ClassLoader#getDefinedPackage(String).

definePackage - An instance of ClassLoader.definePackage(String, String, String, String, String, String, String, URL).

getClassLoadingLock - The accessor method for using ClassLoader#getClassLoadingLock(String) or returning the supplied ClassLoader if this method does not exist on the current VM.
