-/**
- * ll_template_cast<T>(some_value) is for use in a template function when
- * some_value might be of arbitrary type, but you want to recognize type T
- * specially.
- *
- * It's designed for use with pointer types. Example:
- * @code
- * struct SpecialClass
- * {
- *     void someMethod(const std::string&) const;
- * };
- *
- * template <class REALCLASS>
- * void somefunc(const REALCLASS& instance)
- * {
- *     const SpecialClass* ptr = ll_template_cast<const SpecialClass*>(&instance);
- *     if (ptr)
- *     {
- *         ptr->someMethod("Call method only available on SpecialClass");
- *     }
- * }
- * @endcode
- *
- * Why is this better than dynamic_cast<>? Because unless OtherClass is
- * polymorphic, the following won't even compile (gcc 4.0.1):

- * LL_TEMPLATE_CONVERTIBLE(dest, source) asserts that, for a value @c s of
- * type @c source, <tt>ll_template_cast<dest>(s)</tt> will return @c s --
- * presuming that @c source can be converted to @c dest by the normal rules of
- * C++.
- *
- * By default, <tt>ll_template_cast<dest>(s)</tt> will return 0 unless @c s's
- * type is literally identical to @c dest. (This is because of the
- * straightforward application of template specialization rules.) That can
- * lead to surprising results, e.g.:
- *
- * @code
- * Foo myFoo;
- * const Foo* fooptr = ll_template_cast<const Foo*>(&myFoo);
- * @endcode
- *
- * Here @c fooptr will be 0 because <tt>&myFoo</tt> is of type <tt>Foo*</tt>
- * -- @em not <tt>const Foo*</tt>. (Declaring <tt>const Foo myFoo;</tt> would
- * force the compiler to do the right thing.)
- *
- * More disappointingly:
- * @code
- * struct Base {};
- * struct Subclass: public Base {};
- * Subclass object;
- * Base* ptr = ll_template_cast<Base*>(&object);
- * @endcode
- *
- * Here @c ptr will be 0 because <tt>&object</tt> is of type
- * <tt>Subclass*</tt> rather than <tt>Base*</tt>. We @em want this cast to
- * succeed, but without our help ll_template_cast can't recognize it.
- *
- * The following would suffice:
- * @code
- * LL_TEMPLATE_CONVERTIBLE(Base*, Subclass*);
- * ...
- * Base* ptr = ll_template_cast<Base*>(&object);
- * @endcode
- *
- * However, as noted earlier, this is easily fooled:
- * @code
- * const Base* ptr = ll_template_cast<const Base*>(&object);
- * @endcode
- * would still produce 0 because we haven't yet seen:
- * @code
- * LL_TEMPLATE_CONVERTIBLE(const Base*, Subclass*);
- * @endcode
- *
- * @TODO
- * This macro should use Boost type_traits facilities for stripping and
- * re-adding @c const and @c volatile qualifiers so that invoking
- * LL_TEMPLATE_CONVERTIBLE(dest, source) will automatically generate all
- * permitted permutations. It's really not fair to the coder to require
- * separate:
- * @code
- * LL_TEMPLATE_CONVERTIBLE(Base*, Subclass*);
- * LL_TEMPLATE_CONVERTIBLE(const Base*, Subclass*);
- * LL_TEMPLATE_CONVERTIBLE(const Base*, const Subclass*);
- * @endcode
- *
- * (Naturally we omit <tt>LL_TEMPLATE_CONVERTIBLE(Base*, const Subclass*)</tt>
- * because that's not permitted by normal C++ assignment anyway.)

-/**
- * @file   lllazy.h
- * @author Nat Goodspeed
- * @date   2009-01-22
- * @brief  Lazy instantiation of specified type. Useful in conjunction with
- *         Michael Feathers's "Extract and Override Getter" ("Working
- *         Effectively with Legacy Code", p. 352).
- *
- * Quoting his synopsis of steps on p.355:
- *
- * 1. Identify the object you need a getter for.
- * 2. Extract all of the logic needed to create the object into a getter.
- * 3. Replace all uses of the object with calls to the getter, and initialize
- *    the reference that holds the object to null in all constructors.
- * 4. Add the first-time logic to the getter so that the object is constructed
- *    and assigned to the reference whenever the reference is null.
- * 5. Subclass the class and override the getter to provide an alternative
- *    object for testing.
- *
- * It's the second half of bullet 3 (3b, as it were) that bothers me. I find
- * it all too easy to imagine adding pointer initializers to all but one
- * constructor... the one not exercised by my tests. That suggested using
- * (e.g.) boost::scoped_ptr<MyObject> so you don't have to worry about
- * destroying it either.
- *
- * However, introducing additional machinery allows us to encapsulate bullet 4
- * as well.

-/**
- * LLLazy<T> is useful when you have an outer class Outer that you're trying
- * to bring under unit test, that contains a data member difficult to
- * instantiate in a test harness. Typically the data member's class Inner has
- * many thorny dependencies. Feathers generally advocates "Extract and
- * Override Factory Method" (p. 350). But in C++, you can't call a derived
- * class override of a virtual method from the derived class constructor,
- * which limits applicability of "Extract and Override Factory Method." For
- * such cases Feathers presents "Extract and Override Getter" (p. 352).
- *
- * So we'll assume that your class Outer contains a member like this:
- * @code
- * Inner mInner;
- * @endcode
- *
- * LLLazy<Inner> can be used to replace this member. You can directly declare:
- * @code
- * LLLazy<Inner> mInner;
- * @endcode
- * and change references to mInner accordingly.
- *
- * (Alternatively, you can add a base class of the form
- * <tt>LLLazyBase<Inner></tt>. This is discussed further in the LLLazyBase<T>
- * documentation.)
- *
- * LLLazy<T> binds a <tt>boost::scoped_ptr<T></tt> and a factory functor
- * returning T*. You can either bind that functor explicitly or let it default
- * to the expression <tt>new T()</tt>.
- *
- * As long as LLLazy<T> remains unreferenced, its T remains uninstantiated.
- * The first time you use get(), <tt>operator*()</tt> or <tt>operator->()</tt>
- * it will instantiate its T and thereafter behave like a pointer to it.
- *
- * Thus, any existing reference to <tt>mInner.member</tt> should be replaced
- * with <tt>mInner->member</tt>. Any simple reference to @c mInner should be
- * replaced by <tt>*mInner</tt>.
- *
- * (If the original declaration was a pointer initialized in Outer's
- * constructor, e.g. <tt>Inner* mInner</tt>, so much the better. In that case
- * you should be able to drop in <tt>LLLazy<Inner></tt> without much change.)
- *
- * The support for "Extract and Override Getter" lies in the fact that you can
- * replace the factory functor -- or provide an explicit T*. Presumably this
- * is most useful from a test subclass -- which suggests that your @c mInner
- * member should be @c protected.
- *
- * Note that <tt>boost::lambda::new_ptr<T>()</tt> makes a dandy factory
- * functor, for either the set() method or LLLazy<T>'s constructor. If your T
- * requires constructor arguments, use an expression more like
- * <tt>boost::lambda::bind(boost::lambda::new_ptr<T>(), arg1, arg2, ...)</tt>.
- *
- * Of course the point of replacing the functor is to substitute a class that,
- * though referenced as Inner*, is not an Inner; presumably this is a testing
- * subclass of Inner (e.g. TestInner). Thus your test subclass TestOuter for
- * the containing class Outer will contain something like this:
- * @code
- * class TestOuter: public Outer
- * {
- * public:
- *     TestOuter()
- *     {
- *         // mInner must be 'protected' rather than 'private'
- *         mInner.set(boost::lambda::new_ptr<TestInner>());
- *     }
- *     ...
- * };
- * @endcode

-/**
- * LLLazyBase<T> wraps LLLazy<T>, giving you an alternative way to replace
- * <tt>Inner mInner;</tt>. Instead of coding <tt>LLLazy<Inner> mInner</tt>,
- * you can add LLLazyBase<Inner> to your Outer class's bases, e.g.:
- * @code
- * class Outer: public LLLazyBase<Inner>
- * {
- *     ...
- * };
- * @endcode
- *
- * This gives you @c public get() and @c protected set() methods without
- * having to make your LLLazy<Inner> member @c protected. The tradeoff is that
- * you must access the wrapped LLLazy<Inner> using get() and set() rather than
- * with <tt>operator*()</tt> or <tt>operator->()</tt>.
- *
- * This mechanism can be used for more than one member, but only if they're of
- * different types. That is, you can replace:
- * @code
- * DifficultClass mDifficult;
- * AwkwardType    mAwkward;
- * @endcode
- * with:
- * @code
- * class Outer: public LLLazyBase<DifficultClass>, public LLLazyBase<AwkwardType>
- * {
- *     ...
- * };
- * @endcode
- * but for a situation like this:
- * @code
- * DifficultClass mMainDifficult, mAuxDifficult;
- * @endcode
- * you should directly embed LLLazy<DifficultClass> (q.v.).
- *
- * For multiple LLLazyBase bases, e.g. the <tt>LLLazyBase<DifficultClass>,
- * LLLazyBase<AwkwardType></tt> example above, access the relevant get()/set()
- * as (e.g.) <tt>LLLazyBase<DifficultClass>::get()</tt>. (This is why you
- * can't have multiple LLLazyBase<T> of the same T.) For a bit of syntactic
- * sugar, please see getLazy()/setLazy().

- * LLSortedVector contains a std::vector<std::pair> that we keep sorted on the
- * first of the pair. This makes insertion somewhat more expensive than simple
- * std::vector::push_back(), but allows us to use binary search for lookups.
- * It's intended for small aggregates where lookup is far more performance-
- * critical than insertion; in such cases a binary search on a small, sorted
- * std::vector can be more performant than a std::map lookup.

+ * Base* ptr = ll_template_cast<Base*>(&object);
+ * @endcode
+ *
+ * Here @c ptr will be 0 because <tt>&object</tt> is of type

+ * succeed, but without our help ll_template_cast can't recognize it.

+ * @code
+ * LL_TEMPLATE_CONVERTIBLE(Base*, Subclass*);
+ * ...

+ * LL_TEMPLATE_CONVERTIBLE(const Base*, Subclass*);
+ * @endcode
+ *
+ * @TODO
+ * This macro should use Boost type_traits facilities for stripping and

- * * Since we literally use compile-time types as keys, the essential insert()
