Methods in java.lang.invoke with parameters of type MethodType

Modifier and Type	Method and Description
static CallSite	LambdaMetafactory.altMetafactory(MethodHandles.Lookup caller, String invokedName, MethodType invokedType, Object... args) Facilitates the creation of simple "function objects" that implement one or more interfaces by delegation to a provided MethodHandle, after appropriate type adaptation and partial evaluation of arguments.
