Method Detail

• getEnhanceableMethods

  Method[] getEnhanceableMethods()

  Lists the methods in the host class that can be enhanced.

  This always includes public and protected methods that are neither static nor final.

  Package-private methods can only be enhanced if they're in the same package as the host and we can define types in the same class loader with Unsafe. The Object.finalize() method can never be enhanced.

• buildEnhancer

  Function<String,​BiFunction<Object,​Object[],​Object>> buildEnhancer​(BitSet methodIndices)

  Generates an enhancer for the selected subset of methods.

  The enhancer maps constructor and method signatures to invokers, where each invoker is represented as a BiFunction that accepts a context object and an argument array.

  Constructor invokers take an array of InvocationHandlers as their context object. This is stored in the enhanced class before the original host class constructor is called, with arguments unpacked from the argument array. The enhanced instance is then returned.

  Method invokers take an enhanced instance as their context object and call the original super-method with arguments unpacked from the argument array, ie. provides super-invocation.
