class PASCALIMPLEMENTATION TCustomBucketList : public System::TObject
TCustomBucketList is the base class for lists that store items under a limited number of categories.
Use TCustomBucketList as a base class for lists of items that fit into a limited number of categories (or buckets). Each bucket can contain multiple items, and there is a well-defined function (the protected BucketFor method) that determines the bucket into which an item belongs. TCustomBucketList descendants can include lists of items that fall into natural categories, or implementations of a hash table.
