buildEnhancerBuilder	back to summary
public static BytecodeGen.EnhancerBuilder buildEnhancerBuilder(Class<?> hostClass) Builder of enhancers that provide method interception via bytecode generation.

buildFastClass	back to summary
public static Function<String, BiFunction<Object, Object[], Object>> buildFastClass(Class<?> hostClass) Builds a 'fast-class' invoker that uses bytecode generation in place of reflection.

canAccess	back to summary
private static boolean canAccess(Executable member, boolean samePackage) Can we access this member from a subclass which may be in the same package?

canEnhance	back to summary
public static boolean canEnhance(Executable member) Returns true if the given member can be enhanced using bytecode.

canFastInvoke	back to summary
public static boolean canFastInvoke(Executable member) Returns true if the given member can be fast-invoked.

getOverridableObjectMethods	back to summary
private static Method[] getOverridableObjectMethods() Cache common overridable Object methods.

isPublic	back to summary
private static boolean isPublic(Class<?> clazz)

mergeInterface	back to summary
private static boolean mergeInterface(List<Class<?>> interfaces, Class<?> candidate) Attempts to merge the interface with the current flattened hierarchy.

mergeMethods	back to summary
private static Object mergeMethods(Object existing, Object added) Add the new method to an existing partition or create a new one.

packageName	back to summary
private static String packageName(String className) Extract the package name from a class name.

partitionMethod	back to summary
private static void partitionMethod(Method method, Map<String, Object> partitions) Methods are partitioned by name and parameter count. This helps focus the search for bridge delegates that involve type-erasure of generic parameter types, since the parameter count will be the same for the bridge method and its delegate.

pushInterfaces	back to summary
private static void pushInterfaces(Deque<Class<?>[]> interfaceStack, Class<?>[] interfaces) Pushes the interface declaration onto the stack if it's not empty.

signature	back to summary
public static String signature(Constructor<?> constructor) Minimum signature needed to disambiguate constructors from the same host class.

signature	back to summary
public static String signature(Method method) Minimum signature needed to disambiguate methods from the same host class.

signature	back to summary
private static String signature(String name, Class<?>[] parameterTypes) Appends a semicolon-separated list of parameter types to the given name.

visitFastConstructors	back to summary
private static void visitFastConstructors(Class<?> hostClass, Consumer<Constructor<?>> visitor) Visit all constructors for the host class that can be fast-invoked.

visitFastMethods	back to summary
private static void visitFastMethods(Class<?> hostClass, Consumer<Method> visitor) Visit all methods declared by the host class that can be fast-invoked.

visitMembers	back to summary
pack-priv static <T extends Executable> void visitMembers(T[] members, boolean samePackage, Consumer<T> visitor) Visit all subclass accessible members in the given array.

visitMethodHierarchy	back to summary
private static void visitMethodHierarchy(Class<?> hostClass, Consumer<Method> visitor) Visit the method hierarchy for the host class.
