Detailed Description
The KGameProcessIO class.It is used to create a computer player via a separate process and communicate transparetly with it. Its counterpart is the KGameProcess class which needs to be used by the computer player. See its documentation for the definition of the computer player.

Creates a computer player via a separate process. The process name is given as fully qualified filename. Example:

Member Function Documentation
|
The idendification of the IO.
Implements KGameIO. Definition at line 294 of file kgameio.cpp. |
|
Send a message to the process. This is analogous to the sendMessage commands of KGame. It will result in a signal of the computer player on which you can react in the process player.

|
Send a system message to the process. This is analogous to the sendMessage commands of KGame. It will result in a signal of the computer player on which you can react in the process player.

|
Init this device by setting the player and e.g. sending an init message to the device. Calling this function will emit the IOAdded signal on which you can react and initilise the computer player. This function is called automatically when adding the IO to a player. Reimplemented from KGameIO.

|
Notifies the IO device that the player's setTurn had been called Called by KPlayer. You can react on the signalPrepareTurn to prepare a message for the process, i.e. either update it on the changes made to the game since the last turn or the initIO has been called or transmit your gamestatus now.
Reimplemented from KGameIO. Definition at line 321 of file kgameio.cpp. References KPlayer::id(), notifyTurn(), KGameIO::player(), and sendSystemMessage(). Referenced by notifyTurn(). |

Internal message handler to receive data from the process.

|
A computer query message is received. This is a 'dummy' message sent by the process if it needs to communicate with us. It is not forwarded over the network. Reacting to this message allows you to 'answer' questions of the process, e.g. sending addition data which the process needs to calculate a move. Example:

Signal generated when the computer player is added. You can use this to communicated with the process and e.g. send initialisation information to the process.
