- All Implemented Interfaces:
Context
final class XactContext extends ContextImpl
The context associated with the transaction. This object stores the context associated with the raw store transaction on the stack. It stores info about the transaction opened within a context manager (ie. typically a single user) for a single RawStoreFactory.

cleanupOnError
public void cleanupOnError(java.lang.Throwable error) throws StandardException
Description copied from interface:Context
Contexts will be passed errors that are caught by the outer system when they are serious enough to require corrective action. They will be told what the error is, so that they can react appropriately. Most of the time, the contexts will react by either doing nothing or by removing themselves from the context manager. If there are no other references to the context, removing itself from the manager equates to freeing it.
On an exception that is session severity or greater the Context must push itself off the stack. This is to ensure that after a session has been closed there are no Contexts on the stack that potentially hold references to objects, thus delaying their garbage collection.Contexts must release all their resources before removing themselves from their context manager.
The context manager will "unwind" the contexts during cleanup in the reverse order they were placed on its global stack.
If error is an instance of StandardException then an implementation of this method may throw a new exception if and only if the new exception is an instance of StandardException that is more severe than the original error or the new exception is a not an instance of StandardException (e.g java.lang.NullPointerException).
