ExecutionContextThreadedImpl (DataNucleus Core 5.1.13-SNAPSHOT API)

java.lang.Object
- org.datanucleus.ExecutionContextImpl
- - org.datanucleus.ExecutionContextThreadedImpl

All Implemented Interfaces:

ExecutionContextReference, ExecutionContext, TransactionEventListener
```
public class ExecutionContextThreadedImpl
extends ExecutionContextImpl
```
ExecutionContext to attempt to handle multi-threaded PM/EM cases. Locks various methods in an attempt to prevent conflicting thread updates. Note we could have just put this code in ExecutionContextImpl but better to split it out since the majority use-case is to have a non-thread-safe PM/EM. Note also that having thread-safe ExecutionContext usage depends on much more than having this class, since SCO wrappers would need to coordinate with such locks, as would the Transaction for the ExecutionContext. TODO Evaluate all of the places we currently lock (when multithreaded) to find corner cases not caught.
This class *tries to be* thread-safe, but there is no guarantee. You are better advised to design your application to use ExecutionContextImpl for a single thread.
