Methods

### · getAppFile | Summary | Top

       public abstract AppFile getAppFile()

> Returns the AppFile object from which this object was created.

### · getCommand | Summary | Top

       public abstract AppCommand getCommand(String commandName)

> Returns the indicated command. The 'commandName' argument is one of the constants defined in the AppCommand interface. If this instance cannot accept commands of the indicated type, null is returned.
> After retrieving a command using this method, you can add arguments to it, if desired, and then pass the command to the 'performCommand' method to execute the command.

### · getAllCommands | Summary | Top

       public abstract AppCommand[] getAllCommands()

> Returns all the commands which this instance can accept.

### · performCommand | Summary | Top

       public abstract int performCommand(AppCommand command,
                                          int flags)

> Performs the indicated command. If the command is not one of those recognized by this application, an IllegalArgumentException exception is thrown. Returns an error code; if this is non-zero, an error occurred.

> Parameter | Description
> flags | reserved; set to 0

### · move | Summary | Top

       public abstract int move(AppProcess fromProcess,
                                int selector,
                                int flags)

> Used to minimize, maximize this process, or send it in front of or behind other processes, if possible.

> Parameter | Description
> fromProcess | reserved; set to null
> selector | one of the values: APP_MOVE_TOFRONT, APP_MOVE_TOBACK, APP_MOVE_MINIMIZE, APP_MOVE_MAXIMIZE
> flags | reserved; set to 0

### · isRunning | Summary | Top

       public abstract boolean isRunning()

> Indicates whether this instance is indeed still running.

### · getPlatformData | Summary | Top

       public abstract int[] getPlatformData()

> Returns platform-specific data for this process.
> On MRJ/PowerMac, the return array contains the ProcessSerialNumber for this process, lowLongOfPSN in the first element of the array, highLongOfPSN in the second.
> On MS VM/Win95, the return array contains five 32-bit values: the first element of the array contains the HWND for the main window of the main thread of the process, and the next four elements contain the PROCESS_INFORMATION struct from the call to CreateProcess, with 'hProcess' at the second element of the array, etc.
> Other platforms: TBA.
