apply

public static <T,R> Field<R> apply(java.util.function.BiFunction<T,java.lang.Object[],R> fun,

Type Parameters:

T - input field type

R - result field type

Parameters:

fun - the function to apply. It must accept as a first argument the data type carried by the target, and an Object array as second argument (namely, it is a vararg)

fieldTarget - true if the target is a field

fieldIndices - the indexes of which among the arguments are fields
