How is enumerated() constant time O(1)?

I hope this helps . Creating an EnumeratedSequence comes down to initializing its iterator. The latter is done in two steps:
Have a pointer to the base collection or sequence on which enumerated() is called. Initialize the internal variable _count to 0

In Java, when is the constructor for an enumerated constant invoked?

seems to work fine The constructors are invoked when the enum class is initialized. Each constructor will be invoked, in member declaration order, regardless of which members are actually referenced and used.

std::min fails to interpret an enumerated constant as a valid integer type (g++ 4.6.3)

wish of those help your code is alright. template argument deduction does not do conversions (except derived to base), so you get this problem with a simply defined function such as std::min. andrei alexandrescu once wrote a long treatise about what was required, in C++03, to make a template based min function as type lenient as a macro.

Constant enum size no matter the number of enumerated values

this will help In both C and C++, the size of an enum type is implementation-defined, and is the same as the size of some integer type.
A common approach is to make all enum types the same size as int, simply because that's typically the type that makes for the most efficient access. Making it a single byte, for example, would save a very minor amount of space, but could require bigger and slower code to access it, depending on the CPU architecture.
enum foo { zero, one, two };
enum foo obj;
enum foo: unsigned char { zero, one, two };
#include <limits.h>
enum huge { big = INT_MAX, bigger };

Annoying warning: Integer constant not in the range of enumerated type 'UIViewAnimationOptions'

With these it helps You are doing nothing wrong. As you already noticed, the compiler complains because the value is none of the values defined in the enumeration. (The compiler flag -Weverything implies this check.)
You can suppress the warning either by an explicit cast:
options:(UIViewAnimationOptions)(UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat) 
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wassign-enum"
[UIView animateWithDuration:0.5
                      delay:0
                    options:UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat
                 animations:^{
                     self.imgCheckIn.backgroundColor = [UIColor redColor];
                 }
                 completion:nil];
#pragma clang diagnostic pop

Is there a container in Java with constant/log insertion time and constant/log access by index time?
