com.sun.sgs.kernel.AccessCoordinator

A central point for tracking all shared objects accessed in the context of a transaction, and managing any conflict these accesses may cause. In this case, "shared object" means any object that is accessible within any transaction on any node. An example would be a {@code ManagedObject}as provided by the {@code DataService}.

Each {@code sourceName} determines a unique namespace of objects. Any{@link AccessReporter} registered with the same {@code sourceName}through a given {@code AccessCoordinator} instance, independent of the{@code objectIdType}, is considered to report accesses to the same set of shared objects. Conflicting accesses to a single object can be reported to different {@code AccessReporter}s if those reporters were obtained from the same access coordinator using the same source name. Object accesses reported to {@code AccessReporter}s obtained from registering access sources with different names will never conflict.
