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

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

719 // is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below

786 // Also:

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