25 This header defines the dynamic arrays and object arrays (i.e. arrays which
26 own their elements). Dynamic means that the arrays grow automatically as
27 needed.
28
29 These macros are ugly (especially if you look in the sources ;-), but they
30 allow us to define "template" classes without actually using templates and so
31 this works with all compilers (and may be also much faster to compile even
32 with a compiler which does support templates). The arrays defined with these
33 macros are type-safe.
34
35 Range checking is performed in debug build for both arrays and objarrays but
36 not in release build - so using an invalid index will just lead to a crash
37 then.
38
39 Note about memory usage: arrays never shrink automatically (although you may
40 use Shrink() function explicitly), they only grow, so loading 10 millions in
41 an array only to delete them 2 lines below might be a bad idea if the array
42 object is not going to be destroyed soon. However, as it does free memory
43 when destroyed, it is ok if the array is a local variable.

702 // sorted (it uses the COMPARE function)
703 // 3) it has no Sort() method because it's always sorted
704 // 4) Index() method is much faster (the sorted arrays use binary search
705 // instead of linear one), but Add() is slower.
706 // 5) there is no Insert() method because you can't insert an item into the
707 // given position in a sorted array but there is IndexForInsert()/AddAt()
708 // pair which may be used to optimize a common operation of "insert only if
709 // not found"
710 //
711 // Note that you have to specify the comparison function when creating the
712 // objects of this array type. If, as in 99% of cases, the comparison function
713 // is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below

784 // NB1: Base type T should have an accessible copy ctor if Add(T&) is used
