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.

Managing large user selections in an application

An improved source-level debugger for object-oriented application programs which may include linked native language dynamic load libraries. The debugger is compatible with the Java Platform Debugger Architecture (&ldquo;JPDA&rdquo;), and provides new capabilities such as patching of Java variables and reading and writing strings from and to the application under test and being run by a local or remote Java Virtual Machine.
