std::vector< std::string > SamplerFullSolveMultiApp::sampledCommandLineArgs	(	const std::vector< Real > &	row,
		const std::vector< std::string > &	full_args_name
	)

static

Helper for inserting row data into commandline arguments Used here and in SamplerTransientMultiApp.

How it works:

Scalar parameters are done in order of row data: param1;param2;param3 -> param1=row[0] param2=row[1] param3=row[2]
Vector parameters are assigned with brackets: vec_param1[0,1];vec_param2[1,2] -> vec_param1='row[0] row[1]' vec_param2='row[1] row[2]'
Any parameter already with an equal sign is not modified: param1=3.14;param2[0,1,2] -> param1=3.14 param2='row[0] row[1] row[2]'
