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.

708 // 2) the Add() method inserts the item in such was that the array is always
709 // sorted (it uses the COMPARE function)
710 // 3) it has no Sort() method because it's always sorted
711 // 4) Index() method is much faster (the sorted arrays use binary search
712 // instead of linear one), but Add() is slower.
713 // 5) there is no Insert() method because you can't insert an item into the
714 // given position in a sorted array but there is IndexForInsert()/AddAt()
715 // pair which may be used to optimize a common operation of "insert only if
716 // not found"
717 //
718 // Note that you have to specify the comparison function when creating the
719 // objects of this array type. If, as in 99% of cases, the comparison function
720 // is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below

787 // Also:

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