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
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
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
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.
46 // ----------------------------------------------------------------------------

51 The initial size by which an array grows when an element is added default
52 value avoids allocate one or two bytes when the array is created which is

65 less than, equal to or greater than the second one.

75 // NB: for efficiency this often used class has no virtual functions (hence no

77 // won't create any problems because ARRAYs from DEFINE_ARRAY have no dtor
