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.
