30 This header defines the dynamic arrays and object arrays (i.e. arrays which
31 own their elements). Dynamic means that the arrays grow automatically as
34 These macros are ugly (especially if you look in the sources ;-), but they
35 allow us to define "template" classes without actually using templates and so
36 this works with all compilers (and may be also much faster to compile even
37 with a compiler which does support templates). The arrays defined with these
40 Range checking is performed in debug build for both arrays and objarrays but
41 not in release build - so using an invalid index will just lead to a crash
44 Note about memory usage: arrays never shrink automatically (although you may
45 use Shrink() function explicitly), they only grow, so loading 10 millions in
46 an array only to delete them 2 lines below might be a bad idea if the array
47 object is not going to be destroyed soon. However, as it does free memory
48 when destroyed, it is ok if the array is a local variable.
51 // ----------------------------------------------------------------------------

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