aoqi@0 | 33 | * Default implementation of {@link Pipe} that is used as a filter. |
aoqi@0 | 34 | * |
aoqi@0 | 35 | * <p> |
aoqi@0 | 36 | * A filter pipe works on a {@link Packet}, then pass it onto the next pipe. |

aoqi@0 | 39 | * <h2>How do I implement a filter?</h2> |
aoqi@0 | 40 | * <p> |
aoqi@0 | 41 | * Filter {@link Pipe}s are ideal for those components that wish to |
aoqi@0 | 42 | * do some of the followings: |
aoqi@0 | 43 | * |
aoqi@0 | 44 | * <dl> |
aoqi@0 | 45 | * <dt><b> |
aoqi@0 | 46 | * To read an incoming message and perform some work before the |
aoqi@0 | 47 | * application (or more precisely the next pipe sees it) |
aoqi@0 | 48 | * </b> |
aoqi@0 | 49 | * <dd> |
aoqi@0 | 50 | * Implement the {@link #process} method and do some processing before |
aoqi@0 | 51 | * you pass the packet to the next pipe: |
aoqi@0 | 52 | * <pre> |
aoqi@0 | 53 | * process(request) { |
aoqi@0 | 54 | * doSomethingWith(request); |
aoqi@0 | 55 | * return next.process(request); |
aoqi@0 | 56 | * } |
aoqi@0 | 57 | * </pre> |
aoqi@0 | 58 | * |
aoqi@0 | 59 | * |
aoqi@0 | 60 | * <dt><b> |
aoqi@0 | 61 | * To intercept an incoming message and prevent the next pipe from seeing it. |
aoqi@0 | 62 | * </b> |
aoqi@0 | 63 | * <dd> |
aoqi@0 | 64 | * Implement the {@link #process} method and do some processing, |
aoqi@0 | 65 | * then do NOT pass the request onto the next pipe. |
aoqi@0 | 66 | * <pre> |
aoqi@0 | 67 | * process(request) { |
aoqi@0 | 68 | * if(isSomethingWrongWith(request)) |
aoqi@0 | 69 | * return createErrorMessage(); |
aoqi@0 | 70 | * else |
aoqi@0 | 71 | * return next.proces(request); |
aoqi@0 | 72 | * } |
aoqi@0 | 73 | * </pre> |
aoqi@0 | 74 | * |
aoqi@0 | 75 | * <dt><b> |
aoqi@0 | 76 | * To post process a reply and possibly modify a message: |
aoqi@0 | 77 | * </b> |
aoqi@0 | 78 | * <dd> |
aoqi@0 | 79 | * Implement the {@link #process} method and do some processing, |
aoqi@0 | 80 | * then do NOT pass the request onto the next pipe. |
aoqi@0 | 81 | * <pre> |
aoqi@0 | 82 | * process(request) { |
aoqi@0 | 83 | * op = request.getMessage().getOperation(); |
aoqi@0 | 84 | * reply = next.proces(request); |
aoqi@0 | 85 | * if(op is something I care) { |
aoqi@0 | 86 | * reply = playWith(reply); |
aoqi@0 | 87 | * } |
