Detailed Description

Function Documentation

getEnvParam()

template<typename T>

T Rivet::getEnvParam	(	const std::string	name,
		const T &	fallback )

Get a parameter from a named environment variable, with automatic type conversion.

Note

Return fallback if the variable is not defined, otherwise convert its string to the template type

Todo

Should the param name have to be specific to an analysis? Can specialise as an Analysis member fn.
