21 /*
22 This header defines the dynamic arrays and object arrays (i.e. arrays which
23 own their elements). Dynamic means that the arrays grow automatically as
24 needed.
25
26 These macros are ugly (especially if you look in the sources ;-), but they
27 allow us to define "template" classes without actually using templates and so
28 this works with all compilers (and may be also much faster to compile even
29 with a compiler which does support templates). The arrays defined with these
30 macros are type-safe.
31
32 Range checking is performed in debug build for both arrays and objarrays but
33 not in release build - so using an invalid index will just lead to a crash
34 then.
35
36 Note about memory usage: arrays never shrink automatically (although you may
37 use Shrink() function explicitly), they only grow, so loading 10 millions in
38 an array only to delete them 2 lines below might be a bad idea if the array
39 object is not going to be destroyed soon. However, as it does free memory
40 when destroyed, it is ok if the array is a local variable.

346 // 2) the Add() method inserts the item in such was that the array is always
347 // sorted (it uses the COMPARE function)
348 // 3) it has no Sort() method because it's always sorted
349 // 4) Index() method is much faster (the sorted arrays use binary search
350 // instead of linear one), but Add() is slower.
351 // 5) there is no Insert() method because you can't insert an item into the
352 // given position in a sorted array but there is IndexForInsert()/AddAt()
353 // pair which may be used to optimize a common operation of "insert only if
354 // not found"
355 //
356 // Note that you have to specify the comparison function when creating the
