Abstract
Method and apparatus for creating and accessing data objects stored in a portion of the main memory of a data processing system which is inaccessible to programs. The data processing system includes a central processor for executing programs for processing data and a main memory for storing data and programs. The main memory is divided into a program accessible portion and a program inaccessible portion. Vector control objects and vector entries are stored in the program inaccessible portion of the main memory, with each vector entry having states the meaning of which are program defined. Tokens are generated to locate vector control objects in the program inaccessible portion of the main memory. Each vector control object includes a field for pointing to a vector entry for accessing and making observable to the central processor, the contents of a vector entry for indicating the status therein. The present invention also provides for the serialization of access to stored data objects such that the data objects may be released and reused without the possibility of a latent access to an object which is being reused.
