This module implements the data structures which define the cluster |
| 25 | 25 |
operations - the so-called opcodes. |
| 26 | 26 |
|
| 27 |
|
|
| 28 |
This module implements the logic for doing operations in the cluster. There |
|
| 29 |
are two kinds of classes defined: |
|
| 30 |
- opcodes, which are small classes only holding data for the task at hand |
|
| 31 |
- logical units, which know how to deal with their specific opcode only |
|
| 27 |
Every operation which modifies the cluster state is expressed via |
|
| 28 |
opcodes. |
