ExecutionContext (xdi2 0.8-SNAPSHOT API)

java.lang.Object
- xdi2.messaging.container.execution.ExecutionContext

All Implemented Interfaces:

Serializable
```
public final class ExecutionContext
extends Object
implements Serializable
```
Messaging targets as well as contributors and interceptors can use the ExecutionContext to store and share state. The ExecutionContext is created before a MessageEnvelope is executed, and is deleted when execution of the MessageEnvelope is complete. It contains the current position in the execution process, and attributes associated with various stages.
