std::string zypp::iostr::getline

(

std::istream &

str

)

template<class _Function>

_Function& zypp::iostr::forEachLine	(	std::istream &	str_r,
		_Function &	consume_r
	)			[inline]

Simple lineparser: Call functor consume_r for each line.

Parameters:

	str_r	The istream to read from.
	consume_r	A reference to a function or functor. The loop is aborted if the function returns false. bool consume( const std::string & ) { ... } struct Consume : public std::unary_function<const std::string &, bool> { bool operator()( const std::string & line_r ) { ... } };

Returns:

A reference to consume_r.

Todo:

Should be templated and specialized according to the functors return type, to allow void consumer.
