Abstract
The present invention extends to methods, systems, and computer program products for managing object lifetime in a cyclic graph. Embodiments of the invention include reclaiming allocated system resources, for example, from a graph of objects that mixes different resource reclamation techniques (such as reference counting and garbage collection). In response to determining that garbage collection is to be performed, references between GC objects and Ref. Counted objects are detected. A reference type (e.g., direct, indirect, standard, tracked, weakened, etc.) for any detected references is also determined. Garbage collection is performed to determine if any allocated system resources can be reclaimed. Garbage collection considers references and references types between GC objects and Ref. Counted objects when determining if objects are to be reclaimed.
