Interface HGTransactionContext

All Known Implementing Classes:

DefaultTransactionContext

public interface HGTransactionContext

A transaction context maintains a stack of nested transactions. The transaction on top of the stack is the currently active transaction. A beginTransaction will create and push a new transaction on the stack and an endTransaction will remove the top of the transaction stack and commit or abort.

Transaction contexts are useful when implementing a server for HyperGraph. A context can be bound to a client and then get dynamically attached/detach to worker threads using the HGTransactionManager.threadAttach(HGTransactionContext) and HGTransactionManager.threadDetach() methods.
