Member Function Documentation

string Y2ProgramComponent::name

(

)

const [virtual]

Returns the name of this component.

Implements Y2Component.

YCPValue Y2ProgramComponent::evaluate

(

const YCPValue &

command

)

[virtual]

Let the server evaluate a command.

This method is only valid, if the component is a server.

Reimplemented from Y2Component.

void Y2ProgramComponent::result

(

const YCPValue &

result

)

[virtual]

Tells this server, that the client doesn't need it's services any longer and that the exit code of the client is result.

This method is only valid, if the component is a server.

Reimplemented from Y2Component.

void Y2ProgramComponent::setServerOptions	(	int	argc,
		char **	argv
	)			[virtual]

Sets the commandline options of the server.

This method is only valid, if the component is a server.

Reimplemented from Y2Component.

YCPValue Y2ProgramComponent::doActualWork	(	const YCPList &	arglist,
		Y2Component *	user_interface
	)			[virtual]

Launches the program with the previously set parameters

Reimplemented from Y2Component.

void Y2ProgramComponent::sendToExternal

(

const string &

)

YCPValue Y2ProgramComponent::receiveFromExternal

(

)

Receives a YCP value from the external program.

bool Y2ProgramComponent::remote

(

)

const [virtual]

Reimplemented from Y2Component.

void Y2ProgramComponent::launchExternalProgram

(

char **

argv

)

[private]

Lauches the external programm in a new process.

Returns:

true, if this was successful.

void Y2ProgramComponent::terminateExternalProgram

(

)

[private]

Kills the external program (that is process) with SIGQUIT

void Y2ProgramComponent::sendToExternal

(

const YCPValue &

)

[private]

Send a YCP value to the external program

bool Y2ProgramComponent::externalProgramOK

(

)

const [private]

Determines, if the external program is running.

Member Data Documentation

string Y2ProgramComponent::chroot_path [private]

Chroot path for the program.

string Y2ProgramComponent::bin_file [private]

Filename of the executable binary.

bool Y2ProgramComponent::is_non_y2 [private]

Specifies whether this component is a ycp program or a shell and such like.

string Y2ProgramComponent::component_name [private]

Name of the component that is implemented by the program

int Y2ProgramComponent::argc [private]

Stores options for a server program

char** Y2ProgramComponent::argv [private]

Stores options for a server program

int Y2ProgramComponent::to_external[2] [private]
