CommandContext (Teiid 14.0.0 API)

java.lang.Object
- org.teiid.query.util.CommandContext

All Implemented Interfaces:

Cloneable, CommandContext
```
public class CommandContext
extends Object
implements Cloneable, CommandContext
```
Defines the context that a command is processing in. For example, this defines who is processing the command and why. Also, this class (or subclasses) provide a means to pass context-specific information between users of the query processor framework.
