// This is the same as the previous macro, but it defines a sorted array.
|
|
// 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"

|

Also:

<BR>

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)
