  • Method for simultaneous garbage collection and object allocation
    Patent number: 8543987
    Abstract: Disclosed is a method to track allocation of a plurality of objects in a heap. A data processing system, during an object allocation, prevents an object from being moved to another place in memory or being deleted. The data processing system prevents such activity concurrently with garbage collection on a second object not currently being allocated. The data processing system notifies a profiler of object information based on the object allocation via a callback function, wherein object information is a one-to-one mapping of the object address. The data processing system revives garbage collector processing of the object.
    Type: Grant
