/*
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.

// WX_DEFINE_SORTED_TYPEARRAY: this is the same as the previous macro, but it
// defines a sorted array.
//
// Differences:
// 1) it must be given a COMPARE function in ctor which takes 2 items of type
// T* and should return -1, 0 or +1 if the first one is less/greater
// than/equal to the second one.
// 2) the Add() method inserts the item in such was that the array is always
// sorted (it uses the COMPARE function)
// 3) it has no Sort() method because it's always sorted
// 4) Index() method is much faster (the sorted arrays use binary search
// instead of linear one), but Add() is slower.
// 5) there is no Insert() method because you can't insert an item into the
// given position in a sorted array but there is IndexForInsert()/AddAt()
// pair which may be used to optimize a common operation of "insert only if
// not found"
//
// Note that you have to specify the comparison function when creating the
// objects of this array type. If, as in 99% of cases, the comparison function
// is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below
// is more convenient.
//
// Summary: use this class when the speed of Index() function is important, use
// the normal arrays otherwise.

// WX_DECLARE_OBJARRAY(T, name): this macro generates a new array class
// named "name" which owns the objects of type T 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"!
//
// 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
// and so you risk having at least the memory leaks and probably worse
//
// Some functions of this class are not inline, so it takes some space to
// define new class from this template even if you don't use it - which is not
// the case for the simple (non-object) array classes
//
// To use an objarray class you must
// #include "dynarray.h"
// WX_DECLARE_OBJARRAY(element_type, list_class_name)
// #include "arrimpl.cpp"
// WX_DEFINE_OBJARRAY(list_class_name) // name must be the same as above!

// element_type must be fully defined (i.e. forward declaration is not
// enough), while WX_DECLARE_OBJARRAY may be done anywhere. The separation of
// two allows to break cicrcular dependencies with classes which have member
// variables of objarray type.
