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.

673// Differences:
674// 1) it must be given a COMPARE function in ctor which takes 2 items of type
675// T* and should return -1, 0 or +1 if the first one is less/greater
676// than/equal to the second one.
677// 2) the Add() method inserts the item in such was that the array is always
678// sorted (it uses the COMPARE function)
679// 3) it has no Sort() method because it's always sorted
680// 4) Index() method is much faster (the sorted arrays use binary search
681// instead of linear one), but Add() is slower.
682// 5) there is no Insert() method because you can't insert an item into the
683// given position in a sorted array but there is IndexForInsert()/AddAt()
684// pair which may be used to optimize a common operation of "insert only if
685// not found"
686//
687// Note that you have to specify the comparison function when creating the
688// objects of this array type. If, as in 99% of cases, the comparison function
689// is the same for all objects of a class, WX_DEFINE_SORTED_TYPEARRAY_CMP below
690// is more convenient.

742//
743// An element is of type T*, but arguments of type T& are taken (see below!)
744// and T& is returned.
745//
746// Don't use this for simple types such as "int" or "long"!
747//
748// Note on Add/Insert functions:
749// 1) function(T*) gives the object to the array, i.e. it will delete the
750// object when it's removed or in the array's dtor
751// 2) function(T&) will create a copy of the object and work with it
752//
753// Also:
754// 1) Remove() will delete the object after removing it from the array
755// 2) Detach() just removes the object from the array (returning pointer to it)
756//
757// NB1: Base type T should have an accessible copy ctor if Add(T&) is used
758// NB2: Never ever cast a array to it's base type: as dtor is not virtual
759// and so you risk having at least the memory leaks and probably worse
760//
761// Some functions of this class are not inline, so it takes some space to
762// define new class from this template even if you don't use it - which is not
763// the case for the simple (non-object) array classes
764//
765// To use an objarray class you must
766// #include "dynarray.h"
767// WX_DECLARE_OBJARRAY(element_type, list_class_name)
768// #include "arrimpl.cpp"
769// WX_DEFINE_OBJARRAY(list_class_name) // name must be the same as above!

771// This is necessary because at the moment of DEFINE_OBJARRAY class parsing the
772// element_type must be fully defined (i.e. forward declaration is not
773// enough), while WX_DECLARE_OBJARRAY may be done anywhere. The separation of
774// two allows to break cicrcular dependencies with classes which have member
775// variables of objarray type.
