adaptFunctionArray

public static <F,
T> T[] adaptFunctionArray(F[] functionObjects,
 Class<T> functionType,
 Class<Object>... resultSignature)

adaptFunctionList

public static <F,
T> List<T> adaptFunctionList(F[] funcs,
 Class<T> functionType,
 Class<Object>... resultSignature)

adaptFunction

public static <F,
T> T adaptFunction(F func,
 Class<T> functionType,
 Class<?>... resultSignature)

Adapt a functional object into a different type of functional object.

Type Parameters:

F - The generic type of function being converted from

T - The generic type of function being converted to

Parameters:

func - The original function object.

functionType - The type of the function you need

resultSignature - The signature of all output types, linearized for use after type-erasure.

Returns:

An instance of T

getFunctions

public static <T> List<T> getFunctions(int mod,
 int offset,
 Class<? extends T> functionType,
 Object... funcs)

Slice the incoming object list into a set of functions, based on a grouping interval and an offset.

Parameters:

mod - The grouping interval, or modulo to slice the function groups into

offset - The offset within the group for the provided function

funcs - A list of source objects to convert to functions.

Returns:
