System and method for efficiently managing a containment hierarchy

Systems and methods are provided for generating a user interface display on a graphical user interface. Native data is accessed from memory for generating a containment hierarchy, the native data describing features of the user interface display. The containment hierarchy is generated using the accessed native data, the containment hierarchy comprising a plurality of content records, where the containment hierarchy being stored in a system heap. The user interface display is generated by iterating through the plurality of content records of the containment hierarchy. One or more references to one or more content records of the plurality of content records of the containment hierarchy are removed, where the one or more references indicate that the corresponding one or more content records are in use, such that the one or more content records can be reclaimed by garbage collection.
