+//
+// The first (just EXPORTED) macros do it if wxWindows was compiled as a DLL

+// allow the user code to do it when it wants. This is needed if you have a dll
+// that wants to export a wxArray daubed with your own import/export goo.

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

+//
+// An element is of type T*, but arguments of type T& are taken (see below!)

+//
+// Don't use this for simple types such as "int" or "long"!

+// Note on Add/Insert functions:
+// 1) function(T*) gives the object to the array, i.e. it will delete the
+// object when it's removed or in the array's dtor
+// 2) function(T&) will create a copy of the object and work with it
+//
+// Also:
+// 1) Remove() will delete the object after removing it from the array
+// 2) Detach() just removes the object from the array (returning pointer to it)
+//
+// NB1: Base type T should have an accessible copy ctor if Add(T&) is used
+// NB2: Never ever cast a array to it's base type: as dtor is not virtual
+// and so you risk having at least the memory leaks and probably worse
+//
