Description

A collection is an entity that handles a group of objects. This is the base interface for List and Set.

Method Description
Add Add AObject at the end of the collection. Return True if the method succeeds.
AddAll Add all objetcs from ACollection at the end of the collection. Return True if the method succeeds.
Clear Clear all objects contained in the collection.
Contains Return True if the collection contains AObject.
ContainsAll Return True if the collection contains all objects of ACollection.
Equals Return True if all objects of the collection are equal to all objects of ACollection.
First Return a new Iterator from the begin of the collection.
IsEmpty Return True if the collection does not contain any objects.
Last Return a new Iterator from the end of the collection.
Remove Remove AObject from the collection. Return True if the method succeeds.
RemoveAll Remove all objects from the collection contained in ACollection. Return True if the method succeeds.
RetainAll Remove all objects from the collection except all objects contained in ACollection. Return True if the method succeeds.
Size Return the number of objects contained in the collection.
