Parameters:

kill	If true the child process will be killed, otherwise the method waits.

Returns:

Return code of the process.

Implemented in DLVProcess.

virtual std::vector<std::string> Process::commandline

(

)

const [pure virtual]

Returns the whole reasoner commandline call.

Returns:

Command separated into executable and options.

Implemented in DLVProcess.

(

)

[pure virtual]

Sends EOF to the process.

Implemented in DLVProcess.

virtual std::istream& Process::getInput

)

[pure virtual]

Retrieve the input stream of the process.

Returns:

Input stream.

Implemented in DLVProcess.

virtual std::ostream& Process::getOutput

(

)

[pure virtual]

Retrieve the output stream of the process.

Returns:

Output stream.

Implemented in DLVProcess.

virtual std::string Process::path

(

)

const [pure virtual]

Returns the executable command.

Returns:

Reasoner executable command.

Implemented in DLVProcess.

virtual void Process::spawn

(

)

[pure virtual]

Instantiates a new process spawned from this one.

Implemented in DLVProcess.

virtual void Process::spawn

(

const std::vector< std::string > &
