Method Detail

addTransformer

protected static MethodHandle addTransformer(MethodHandle handle,
                          int pos,
                          Object arg,
                          Class parameter)

Adds a type transformer applied at runtime. This method handles transformations to String from GString, array transformations and number based transformations

applyUnsharpFilter

public static MethodHandle applyUnsharpFilter(MethodHandle handle,
                              int pos,
                              MethodHandle transformer)

Apply a transformer as filter. The filter may not match exactly in the types. In this case needed additional type transformations are done by MethodHandle.asType(MethodType)
