The present invention provides a system and methods for managing large user selections in an application. An invertible collection software module solves the problem of managing a large number of user selections within an application. When not inverted, the invertible collection tracks what a user has selected. When inverted, the invertible collection tracks what a user has not selected thus saving memory. One method may comprise defining a specific context having a set of items available for user selection, representing, by an empty inverted invertible collection, the selection of all items within the specific context, tracking one or more items a user has deselected within the specific context depending upon whether the collection is inverted or not inverted and tracking one or more items a user has deselected.
A method for managing large user selections comprising:
A system for managing large user selections of items, the system comprising:
A computer program product embodied in a computer readable hardware storage device for operating in a system comprising a processing unit, a memory, a bus, input/output (I/O) interfaces, an application, an empty inverted invertible collection, and a collection, the computer program product for implementing a method for managing large user selections of items comprising:
