+/*
+ This header defines the dynamic arrays and object arrays (i.e. arrays which
+ own their elements). Dynamic means that the arrays grow automatically as
+ needed.
+
+ These macros are ugly (especially if you look in the sources ;-), but they
+ allow us to define "template" classes without actually using templates and so
+ this works with all compilers (and may be also much faster to compile even
+ with a compiler which does support templates). The arrays defined with these
+ macros are type-safe.
+
+ Range checking is performed in debug build for both arrays and objarrays but
+ not in release build - so using an invalid index will just lead to a crash
+ then.
+
+ Note about memory usage: arrays never shrink automatically (although you may
+ use Shrink() function explicitly), they only grow, so loading 10 millions in
+ an array only to delete them 2 lines below might be a bad idea if the array
+ object is not going to be destroyed soon. However, as it does free memory
+ when destroyed, it is ok if the array is a local variable.

-
-
- Range checking is performed in debug build for both arrays and objarrays.
- Type checking is done at compile-time. Warning: arrays never shrink,
- they only grow, so loading 10 millions in an array only to delete them 2
- lines below is not recommended. However, it does free memory when
- it's destroyed, so if you destroy array also, it's ok.

- This macro generates a new objarrays class which owns the objects it
- contains, i.e. it will delete them when it is destroyed. An element is of
- type T*, but arguments of type T& are taken (see below!) and T& is
- returned.
- Don't use this for simple types such as "int" or "long"!
- You _may_ use it for "double" but it's awfully inefficient.
-
-
- Note on Add/Insert functions:
-
- 1) function(T*) gives the object to the array, i.e. it will delete the
- object when it's removed or in the array's dtor
-
- 2) function(T&) will create a copy of the object and work with it
-
-
- Also:
-
- 1) Remove() will delete the object after removing it from the array
-
- 2) Detach() just removes the object from the array (returning pointer to it)
-
-
- NB1: Base type T should have an accessible copy ctor if Add(T&) is used,
-
- NB2: Never ever cast a array to it's base type: as dtor is not virtual
- it will provoke memory leaks
-
-
- some functions of this class are not inline, so it takes some space to
- define new class from this template.
