ASetis aCollectionthat cannot contain duplicate elements. It models the mathematical set abstraction. TheSetinterface containsonlymethods inherited fromCollectionand adds the restriction that duplicate elements are prohibited.Setalso adds a stronger contract on the behavior of theequalsandhashCodeoperations, ...
this set if the set contains no elemente2such that(e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returnsfalse. In combination with the restriction on constructors, this ensures that sets never contain duplicate ...
A Map is a data structure that maps keys to values. A map cannot contain duplicate keys and each key can map to at most one value. Implements Container interface. type Map interface { Put(key interface{}, value interface{}) Get(key interface{}) (value interface{}, found bool) Remove(...
To allow duplicate values, use the all=True argument. union(), intersection(), and difference() return model instances of the type of the first QuerySet even if the arguments are QuerySets of other models. Passing different models works as long as the SELECT list is the same in all ...
Unordered, Repeating Group Of Values (Multiset) Creates a collection of elements that can have duplicate values. The elements do not have ordinal positions. Click OK to close the Column Properties dialog box. Create a composite data type with the Type shape The Database Model ...

A SortedSet<T> object maintains a sorted order without affecting performance as elements are inserted and deleted. Duplicate elements are not allowed. Changing the sort values of existing items is not supported and may lead to unexpected behavior....
Indicates whether the deduplication engine performs a byte-for-byte verification for each duplicate chunk that optimization creates, rather than relying on a cryptographically strong hash. We do not recommend that you use this parameter. Setting this parameter to $True can degrade optimization performanc...
Otherwise, the destination database may contain duplicate data records. If you select collections as the objects to be migrated and you need to edit collections in the destination database, such as renaming collections, up to 1,000 collections can be migrated in a ...
