MANAGING LARGE USER SELECTIONS IN AN APPLICATION

摘要

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.

主权项

1. A method for managing large user selections comprising:
defining a specific context having a set of items available for user selection, each of the set of items representing a different selectable option corresponding to an action within an application; representing, by an empty inverted invertible collection, the selection of all items within the specific context; storing, as a collection, in a storage device operable with the application, only one or more items a user has deselected within the specific context; and tracking the collection within the storage device of the one or more items the user has deselected.
