| * An instance of this class represents a request to handle a command. A handler |
| * submission specifies a list of conditions under which it would be appropriate |
| * for a particular command to have a particular handler. These conditions |
| * include things like the active part or the active shell. So, it is possible |
| * to say things like: "when my part is active, please consider calling these |
| * classes when you want to perform a cut, copy or paste". |
| * </p> |
| * <p> |
| * The workbench considers all of the submissions it has received and choses the |
| * ones it views as the best possible match. |
| * </p> |
| * <p> |
| * This class is not intended to be extended by clients. |
| * </p> |
| * <p> |
| * Note: this class has a natural ordering that is inconsistent with equals. |
