Class Description

                                                                      
 TObjArray                                                            
                                                                      
 An array of TObjects. The array expands automatically when           
 objects are added (shrinking can be done by hand using Expand(),     
 how nice to have meaningful names -:)).                              
 Use operator[] to have "real" array behaviour.

 Create an object array. Using s one can set the array size (default is
 kInitCapacity=16) and lowerBound can be used to set the array lowerbound
 index (default is 0).

 Create a copy of TObjArray a.

 Delete an array.

 Add object in the first slot of the array. This will overwrite the
 first element that might have been there. To have insertion semantics
 use either a TList or a TOrdCollection.

 Add object in the next empty slot in the array. Expand the array
 if necessary.

 Add object in the slot before object before. If before=0 add object
 in the first slot. Note that this will overwrite any object that
 might have already been in this slot. For insertion semantics use
 either a TList or a TOrdCollection.

 Add object in the slot after object after. If after=0 add object in
 the last empty slot. Note that this will overwrite any object that
 might have already been in this slot. For insertion semantics use
 either a TList or a TOrdCollection.

 Add object at position idx. If idx is larger than the current size
 of the array, expand the array (double its size).

 Add object at position ids. Give an error when idx is out of bounds
 (i.e. the array is not expanded).

 Return the position of the new object.
 Find the first empty cell or AddLast if there is no empty cell

 Return the object after obj. Returns 0 if obj is last object.

 Return the object at position i. Returns 0 if i is out of bounds.

 Return the object before obj. Returns 0 if obj is first object.

 Remove all objects from the array. Does not delete the objects.

 Remove empty slots from array.

 Remove all objects from the array AND delete all heap based objects.

 Expand or shrink the array to newSize elements.

 Stream all objects in the array to or from the I/O buffer.

 Return the object in the first slot.

 Return the object in the last filled slot. Returns 0 if no entries.

 Return the number of objects in array (i.e. number of non-empty slots).
 Attention: use this method ONLY if you want to know the number of
 non-empty slots. This function loops over the complete array and
 is therefore very slow when applied in a loop. Most of the time you
 better use GetLast()+1.

 Return absolute index to last object in array. Returns -1 in case
 array is empty.

 Return index of last object in array. Returns lowerBound-1 in case
 array is empty.

 obj != 0 Return index of object in array.
          Returns lowerBound-1 in case array doesn't contain the obj.

 obj == 0 Return the index of the first empty slot.
          Returns lowerBound-1 in case array doesn't contain any empty slot.

 Initialize a TObjArray.

 Returns an array iterator.

 Generate an out-of-bounds error. Always returns false.

 Remove object at index idx.

 Remove object from array.

 Set index of last object in array, effectively truncating the
 array. Use carefully since whenever last position has to be
 recalculated, e.g. after a Remove() or Sort() it will be reset
 to the last non-empty slot.

 If objects in array are sortable (i.e. IsSortable() returns true
 for all objects) then sort array.

 Find object using a binary search. Array must first have been sorted.
 Search can be limited by setting upto to desired index.
