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 continuously managing only the collection within the storage device of the one or more items the user has deselected, wherein all other items of the large user selections not stored in the collection are not monitored; wherein the application, the empty inverted invertible collection, and the collection are separate entities; and wherein the application is connected to empty inverted invertible collection via a first connection, and the empty inverted invertible collection is connected to the collection via a second connection.
