30 This header defines the dynamic arrays and object arrays (i.e. arrays which
31 own their elements). Dynamic means that the arrays grow automatically as
32 needed.
33
34 These macros are ugly (especially if you look in the sources ;-), but they
35 allow us to define "template" classes without actually using templates and so
36 this works with all compilers (and may be also much faster to compile even
37 with a compiler which does support templates). The arrays defined with these
38 macros are type-safe.
39
40 Range checking is performed in debug build for both arrays and objarrays but
41 not in release build - so using an invalid index will just lead to a crash
42 then.
43
44 Note about memory usage: arrays never shrink automatically (although you may
45 use Shrink() function explicitly), they only grow, so loading 10 millions in
46 an array only to delete them 2 lines below might be a bad idea if the array
47 object is not going to be destroyed soon. However, as it does free memory
48 when destroyed, it is ok if the array is a local variable.

677//
678// Differences:
679// 1) it must be given a COMPARE function in ctor which takes 2 items of type
680// T* and should return -1, 0 or +1 if the first one is less/greater
681// than/equal to the second one.
682// 2) the Add() method inserts the item in such was that the array is always
683// sorted (it uses the COMPARE function)
684// 3) it has no Sort() method because it's always sorted
685// 4) Index() method is much faster (the sorted arrays use binary search
686// instead of linear one), but Add() is slower.
687// 5) there is no Insert() method because you can't insert an item into the
688// given position in a sorted array but there is IndexForInsert()/AddAt()
689// pair which may be used to optimize a common operation of "insert only if
690// not found"
691//
692// Note that you have to specify the comparison function when creating the
693// objects of this array type. If, as in 99% of cases, the comparison function
694// is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below
695// is more convenient.
696//
697// Summary: use this class when the speed of Index() function is important, use
698// the normal arrays otherwise.

747//
748// An element is of type T*, but arguments of type T& are taken (see below!)
749// and T& is returned.
750//
751// Don't use this for simple types such as "int" or "long"!
752//
753// Note on Add/Insert functions:
754// 1) function(T*) gives the object to the array, i.e. it will delete the
755// object when it's removed or in the array's dtor
756// 2) function(T&) will create a copy of the object and work with it
757//
758// Also:
759// 1) Remove() will delete the object after removing it from the array
760// 2) Detach() just removes the object from the array (returning pointer to it)
761//
762// NB1: Base type T should have an accessible copy ctor if Add(T&) is used
763// NB2: Never ever cast a array to it's base type: as dtor is not virtual
764// and so you risk having at least the memory leaks and probably worse
765//
766// Some functions of this class are not inline, so it takes some space to
767// define new class from this template even if you don't use it - which is not
768// the case for the simple (non-object) array classes
769//
770// To use an objarray class you must
771// #include "dynarray.h"

773// #include "arrimpl.cpp"
774// WX_DEFINE_OBJARRAY(list_class_name) // name must be the same as above!

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