Method Detail

addTransformer	back to summary
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	back to summary
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)`

createSAMTransform	back to summary
private static MethodHandle createSAMTransform(Object arg, Class<?> parameter) creates a method handle able to transform the given Closure into a SAM type if the given parameter is a SAM type

selectNumberTransformer	back to summary
private static MethodHandle selectNumberTransformer(Class<?> param, Object arg) returns a transformer later applied as filter to transform one number into another
