Detailed Description

The KGameProcessIO class.

It is used to create a computer player via a separate process and communicate transparently 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.

Definition at line 351 of file kgameio.h.

Constructor & Destructor Documentation

◆ KGameProcessIO()

KGameProcessIO::KGameProcessIO ( const QString & name )

explicit

Creates a computer player via a separate process.

The process name is given as fully qualified filename. Example:

KGameProcessIO *input;
  input=new KGameProcessIO(executable_file);
 connect(input,SIGNAL(signalPrepareTurn(QDataStream &,bool,KGameIO *,bool *)),
         this,SLOT(slotPrepareTurn(QDataStream &,bool,KGameIO *,bool *)));
 connect(input,SIGNAL(signalProcessQuery(QDataStream &,KGameProcessIO *)),
         this,SLOT(slotProcessQuery(QDataStream &,KGameProcessIO *)));

Parameters

name	the filename of the process to start

Definition at line 260 of file kgameio.cpp.

◆ ~KGameProcessIO()

KGameProcessIO::~KGameProcessIO ( )

override

Deletes the process input devices.

Definition at line 288 of file kgameio.cpp.

Member Function Documentation

◆ initIO()

void KGameProcessIO::initIO ( KPlayer * p )

overridevirtual

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.

Definition at line 308 of file kgameio.cpp.

◆ notifyTurn()

void KGameProcessIO::notifyTurn ( bool turn )

overridevirtual

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.

Parameters

turn	is true/false

Reimplemented from KGameIO.

Definition at line 328 of file kgameio.cpp.

◆ receivedMessage

void KGameProcessIO::receivedMessage ( const QByteArray & receiveBuffer )

protectedslot

Internal message handler to receive data from the process.

Definition at line 387 of file kgameio.cpp.

◆ rtti()

int KGameProcessIO::rtti ( ) const

overridevirtual

The identification of the IO.

Returns: ProcessIO

Implements KGameIO.

Definition at line 303 of file kgameio.cpp.

◆ sendAllMessages()

void KGameProcessIO::sendAllMessages	(	QDataStream &	stream,
		int	msgid,
		quint32	receiver,
		quint32	sender,
		bool	usermsg )

protected

Internal combined function for all message handling.

Definition at line 356 of file kgameio.cpp.

◆ sendMessage()

void KGameProcessIO::sendMessage	(	QDataStream &	stream,
		int	msgid,
		quint32	receiver,
		quint32	sender )

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.

Parameters

stream	- the actual data
msgid	- the id of the message
receiver	- not used
sender	- who send the message

Definition at line 351 of file kgameio.cpp.

◆ sendSystemMessage()

void KGameProcessIO::sendSystemMessage	(	QDataStream &	stream,
		int	msgid,
		quint32	receiver,
		quint32	sender )

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.

Parameters

stream	- the actual data
msgid	- the id of the message
receiver	- not used
sender	- who send the message

Definition at line 346 of file kgameio.cpp.

◆ signalIOAdded

void KGameProcessIO::signalIOAdded	(	KGameIO *	game,
		QDataStream &	stream,
		KPlayer *	p,
		bool *	send )

signal

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.

Parameters

game	the KGameIO object itself
stream	the stream into which the move will be written
p	the player itself
send	set this to false if no move should be generated

◆ signalProcessQuery

void KGameProcessIO::signalProcessQuery	(	QDataStream &	stream,
		KGameProcessIO *	me )

signal

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:

void GameWindow::slotProcessQuery(QDataStream &stream,KGameProcessIO *reply)
{
  int no;
  stream >> no;  // We assume the process sends us an integer question number
  if (no==1)     // but YOU have to do this in the process player
  {
    QByteArray buffer;
    QDataStream out(buffer,QIODevice::WriteOnly);
    reply->sendSystemMessage(out,4242,0,0);  // lets reply something...
  }
}

◆ signalReceivedStderr

void KGameProcessIO::signalReceivedStderr ( const QString & msg )

signal

Text is received by the process on STDERR.

This is usually a debug string.

Parameters

msg The text
