| /** | ||
| * A generic network packet that allows a client-side GUI (or container) to talk to its server-side container. | ||
| * <p> | ||
| * Usage: | ||
| * <ul> | ||
| * <li>On the GUI implement IRemoteExec.IGui (already done on GuiContainerBaseEIO). | ||
| * <li>On the container implement IRemoteExec.IContainer. | ||
| * <li>If needed, add a new send() method and PATTERN to GuiPacket for the correct number and type of parameters. | ||
| * <li>If needed, add a new DataType value and handling code to GuiPacket (for things that cannot be transmitted as int or long). | ||
| * <li>In the GUI, call the appropriate send() method. Chose a unique (per container) message ID. | ||
| * <li>In the container, implement networkExec() and switch on the message ID. You can get the parameters with the same index numbers as the send() method put | ||
| * them in. Be careful to match the data types used or you'll get either 0 values. | ||
| * <li>Done. | ||
| * </ul> | ||
| * | ||
| * The GuiPacket's handler will make sure that calls are only delivered to the correct container. If that container isn't open, the message will be silently | ||
| * ignored. | ||
| * <p> | ||
| * The GUI and container are responsible to agree on the data transferred. | ||
