class TRefArray: public TSeqCollection

 default constructor

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

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

 Create a copy of TRefArray a.

 Assignment operator.

 Usual destructor (The object pointed to by the array are never deleted).

 Private/static function, check for validity of pid.

 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 before obj. Returns 0 if obj is first object.

 Remove all objects from the array.

 Remove empty slots from array.

 Remove all objects from the array and free the internal memory.

 Expand or shrink the array to newSize elements.

the reference may be in the TRefTable

 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.

 Return address of pointer obj.

 Return UID of element at.

 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 TRefArray.

 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 last is -2 this will force the
 recalculation of the last used 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.

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