TdxFastList.Pack(Pointer) Method

Removes redundant pointers from the list.

Declaration

procedure Pack(APattern: Pointer = nil);

Parameters

Name	Type
APattern	Pointer

Remarks

Call this procedure to delete all nil (in Delphi) or NULL/nullptr (in C++Builder) pointers from the list. You can use the APattern optional parameter to delete all stored pointers that match it instead of nil or NULL/nullptr pointers. The Pack procedure:

• Decrements the Count property value by the number of deleted redundant pointers.

• Shifts each block of remaining pointers that follow each deleted pointer left by one position towards the list’s beginning to form a single contiguous occupied memory block.

Note

A Pack procedure call has no effect if the ordered pointer list is empty or stores no pointers that match the specified pattern.
