All Implemented Interfaces:

ExecutableCommand
```
public class CompoundCommand
extends ExecutableCommandWrapper
```
A group of commands used to minimize the number of executions between a Java program and the Integrity server.

A compound command might be used to group the execution of nested commands, to minimize the communication between the Java program and the Integrity server and to improve performances.

This compound command will automatically decide which set of commands can be grouped together. For example, commands that modify the fields of the same Item can be grouped together for a unique execution.

If nested commands cannot be grouped, they will be executed sequentially. So using a CompoundCommand even in that case would not introduce extra overhead.
